Tech Stuff - Ipv6

Version 6 of the IP Protocol. Defined in RFC 2460 (and updated by RFC5095 and RFC5722). Everything about IPv6 is BIG. An IPv4 address is 32 bits, an IPv6 address is 128 bits. This is about the number where each blade of grass on the planet could have its own IPv6 address.

IPv6 has been around since at least 1995 but the CIDR initiative of the mid-nineties pushed back any, then pressing, need for IPv6's increased address range. The can was effectively kicked down the road. In retrospect this was probably a Good Thing ™ since much of the recent (2010/2015) IPv6 work has been to reduce IPv6 address complexity, interworking and overall functionality.

IPv6 is big and complex in comparison with IPv4. This fact alone will keep users from implementation if they have any choice in the matter. Nevertheless, the internet is rapidly approaching the time - primarily due to IPv4 address depletion - when there is little choice but to move to IPv6. The transition will be accompanied by much yelling, screaming, gnashing of teeth and grim resignation. It is not helped by the constant roll-back and fiddling with the IPv6 specifications.

More Info

Here are some of the reasons we need to transition to IPv6:

  1. The 3GPP (3rd Generation Partnership Project) decision to use IPv6 for increasingly functional mobile equipment.
  2. 8 of the 13 DNS root-servers are advertising both IPv4 and IPv6 access (abfhjklm - as of 2010).
  3. Increasing demand for end user address transparency, for example, VoIP.
  4. Widespread availability of IPv6 protocol stacks for almost all major OS platforms.
  5. Increasingly dire warnings (2010) from the major Regional Internet Registries (RIRs), responsible for Internet address allocation, about depletion of IPv4.

The IPv4 vs IPv6 debate is also about the bigger issue of end user transparency vs NAT. Between those who see NAT as being inherently evil - since it hides end user addresses thus removing address transparency (using a variety of simple to gruesome techniques) - and those who see NAT as being a life saving technology that may indefinitely postpone the need for IPv6.

To be truly useful IPv6 must also finally remove the need for end users to know anything about their IP address as a matter of routine - simply because it will be impossible for any sane human being to remember one of these gruesome strings of digits. Imagine asking your Father to read his IPv6 address over the phone. Got the picture. DNS and DHCPv6 can work seemlessly to make the IP address disappear at the user level and auto-configuration (stateless or SLAAC configuration) can simplify address allocation. For IPv6 to work we must treat any need for a visible IP address as a system failure.

IPv6 may have been, to use an unattributed quote, "too much, too early" and certainly the latest RFCs try and back-pedal from some of the earlier specification constraints and functionality (frequently making them even more complex to read if that is possible). Nevertheless, there are a significant number of implementations, proving IPv6 is a production ready technology. Much of the new IPv6 work appearing in the RFCs is, apart from routine maintenance, concerned with the impact of IPv6 in the tightly constrained mobile world.

It is noted that RFC 6540 (published April 2012) now formally suggests that best practice protocol stacks should now include both IPv6 and IPv4. While IPv6 and IPv4 have been available, for many years, with mainstream OSs (Linux, BSD, Windows and others) and, due to its application in the mobile world, Android and other mobile centric OSs, most network boxes (DSL/cable modems) are still IPv4 only. High quality Open Source IPv6 stacks and this nudging from the IETF may change this. Then again, perhaps holding one's breath may not be a sensible strategy just yet since it will be many years before all that IPv4 NAT investment used by most ISPs will obsolete IPv4 functionality.

IPv6 Overview

First things first. Each PC - more properly each network interface - may have more than one IPv6 address - IPv6 is naturally multi-homed. Second, an IPv6 address has a scope, that is, it can be restricted to a single LAN or a private network or be globally unique. The following table defines the types of IPv6 addresses that can be supported and contrasts them with their closest IPv4 functional equivalent.

IPv6 Name Scope/Description IPv4 Equivalent Notes
Link-Local Local LAN only. Automatically assigned based on MAC. Cannot be routed outside local LAN. No real equivalent. Assigned IPv4 over ARP'd MAC. Scoped address concept new to IPv6. Multicast may also be scoped to link-local (RFC 4489). Format.
Site-Local Optional. Local Site only. Cannot be routed over Internet. Assigned by user. Private network address with multi-homed interface is closest equivalent. Scoped address concept new to IPv6. Unlike the IPv4 private network address the IPv6 device can have, and most likely will have, Link-Local, Site-Local and a Global Unicast address. Site-Local while continuing to exist in the IPv6 specification is the subject of on-going work in the IETF and is currently not supported. The address block used for this purpose has been marked Reserved by IANA.
Global Unicast Globally unique. Fully routable. Assigned by IANA/Regional Internet Registries (RIRs). Global IP address. IPv6 and IPv4 similar but IPv6 can have other scoped addresses. Format.
Multicast One-to-many. Hierarchy of multicasting. Similar to IPv4 Class D. Significantly more powerful than IPv4 version. No broadcast in IPv6, replaced by multicast. Multicast may also be scoped to link-local (RFC 4489). Format.
Anycast One-to-nearest. Uses Global Unicast Addresses. Routers only. Discovery uses. Unique protocols in IPv4, for example, IGMP. Addresses are indistinguishable froma normal unicast address. Anycast (router-to-router) is also used with IPv4 addresses, specifically with DNS root servers, though there may be other instances.
Loopback Local interface scope. Same as IPv4 127.0.0.1 Same function

IPv6 Address Notation

An IPv6 address consists of 128 bits - an IPv4 address consists of 32 bits - and is written as a series of 8 hexadecimal strings separated by colons. (Format defined by RFC 4291 and updated by RFC 5952) Examples:

# all the following refer to the same address
2001:0000:0234:C1AB:0000:00A0:AABC:003F
# leading zeros can be omitted
2001:0:234:C1AB:0:A0:AABC:3F
# not case sensitive - any mixture allowed
2001:0:0234:C1ab:0:A0:aabc:3F

One or more zeros entries can be omitted entirely but only once in an address. The user can choose the most efficient place to omit multiple zero entries. Examples:

# raw ipv6 address
2001:0000:0234:C1AB:0000:00A0:AABC:003F
# address with single 0 dropped
2001::0234:C1ab:0:A0:aabc:003F
# alternate version - address with single 0 dropped
2001:0:0234:C1ab::A0:aabc:003F
# the following is INVALID
2001::0234:C1ab::A0:aabc:003F

Multiple zeros can be omitted entirely but only once in an address. Examples:

# omitting multiple 0's in address
2001:0:0:0:0:0:0:3F
# can be written as
2001::3F
# lots of zeros (loopback address)
0:0:0:0:0:0:0:1
# can be written as
::1
# all zeros (unspecified a.k.a unassigned IP)
0:0:0:0:0:0:0:0
# can be written as
::
# but this address
2001:0:0:1:0:0:0:3F
# cannot be reduced to this 
2001::1::3F  # INVALID
# instead it can only be reduced to
2001::1:0:0:0:3F
# or 
2001:0:0:1::3F

Experiment using the IPv6 Address Calculator.

A hybrid format may be used when dealing with IPv6 - IPv4 addresses called an IPv4-Mapped IPv6 Address (RFC 4291 - updated by RFC 5952 and RFC 6052) where the normal IPv4 dotted decimal notation may be used after the first 6, 16 bit address elements:

# generic IPv6-IPv4 format x.x.x.x.x.x.d.d.d.d
# example of an IPv4 mapped IPv6 address
# with an IPv4 number of 192.168.0.5
2001:db8:0:0:0:0:FFFF:192.168.0.5
# or using zero elimination
2001.db8::FFFF:192.168.0.5

Experiment using the IPv6 Address Calculator.

Notes:

  1. The FFFF element in the 6th position is fixed and must be present (see also RFC 6052 for a peculiar shifted version of this format when used with certain IPv4/IPv6 translators).

  2. To avoid publication of a global IPv4 the example above shows a private (non-globally unique) IPv4 address purely to illustrate the principle but the IPv4 address used in IPv4-Mapped IPv6 must always be globally unique address.

IPv6 Prefix or Slash Notation

IPv6 uses a similar / (forward slash) notation to IPv4 CIDR (Classless Interdomain Routing) which describes the number of contiguous bits used in its netmask. Formally this way of writing an address is called an IP prefix but more commonly called the slash format. Examples:

# single user address
2001:db8::1/128
# normal user IPv6 address allocation 
# allows the user to control the low order 80 bits
2001:db8::/48
# values only required to cover the prefix
FE8::/10
# or top 3 bits only with fixed value 001 (binary)
2::/3

IPv6 Address Types

The type of IP address is defined by a variable number of the top bits known as the binary prefix (BP). Only as many bits as required are used to identify the address type as shown in the following table (defined in RFC 4291):

Use Binary Prefix Slash Description/Notes
Unspecified 00...0 ::/128 IPv6 address = 0:0:0:0:0:0:0:0 (or ::) Used before an address allocated by DHCP (equivalent of IPv4 0.0.0.0)
Loopback 00...1 ::1/128 IPv6 address = 0:0:0:0:0:0:0:1 (or ::1) Local PC Loopback (equivalent of IPv4 127.0.0.1)
Multicast 1111 1111 FF::/8 Format. There is now a link-local multicast format defined by RFC 4489.
Link-Local unicast 1111 1110 10 FE8::/10 Local LAN scope. Lower bits (EUI-64) created from MAC address or other Interface Identifier. Format. There is now a link-local multicast format defined by RFC 4489.
Site-Local unicast 1111 1110 11 FEC::/10 Local Site scope. Lower bits assigned by user. This binary prefix has been marked Reserved by IANA to reflect the currently unsupported state of Site-Local addressing.
Global Unicast All other values 2::/3 A note in RFC 3513 recommended that IANA should continue to allocate only from the binary prefix 001 (as in RFC 2373 version) but RFC 3587 obsoletes this recommendation. Format.

The revised definition is a conceptual change and is both more flexible than the previous (RFC 2373/RFC 3513) definition if a tad confusing. IPv4 and NSAP prefixes are still allowed for but are now simply unicast addresses. Subsequent changes (from RFC 3513 to RFC 4291) seem to be trying to remove some of the restrictions previously imposed such that RFCs now use the distinction between a binary prefix of 000 (covering IPv6 mapped IPv4, unassigned and loopback) and not 000 (all other unicast) rather than explicity using 001 as previously. The obsolescence of address block assignment from the previous binary prefix 001 seems to be of a theoretical nature since all current IANA address block assigments are still from this prefix.

IPv6 Global Unicast Address Format

The IPv6 Global Unicast 128 bits was historically divided into a 48 bit global routing prefix (a.k.a site prefix) which is assigned by various authorities, a 16 bit subnet ID and 64 bits which the Interface ID (IID). The 16 bit subnet ID and IID (a total of 80 bits) is normally assigned and used by the user. While this structure is still the normal address allocation, the standards (RFC 4291) now define both the global routing prefix and the subnet ID to be of variable length (and using a total of 64 bits) in order to allow greater flexibility for the RIRs in allocating addresses. The formal structure is therefore:

Name Size Description/Notes
GRP Variable Global Routing Prefix. Variable format depending on the Binary Prefix, for instance, if 001 - Global Unicast Address (assigned by IANA) uses this format. See note about current standards structure above. Normally this part is 48 bits in length but - depending on RIR policies - can be as long as 56 bits.
subnet ID Variable Used for subnet routing. See notes about current standards structure above. Normally this part is 16 bits in length but - depending on RIR policies - can be as low as 8 bits or 0 is the user only requires a single subnet.
interface ID 64 bits The unique interface identifier (host address equivalent in IPv4).

The current IPv6 address allocation policy adopted by the various Regional Internet Registries should be based on the IETF/IAB recomendation (in RFC 3177) which allows for:

Name Allocation Description/Notes
Normal User /48 May cover home or business use. The user controls the full 80 bits addresses comprising the subnet ID (16 bits) and Interface ID (IID - 64 bits). Regional (RIRs) or Local Internet Registries (LIRs) seem to be able to allocate a /56 in which case the subnet is defined to be 8 bits and the IID remains, as normal, 64 bits. It is not clear under what circustances /56 addresses are allocated other than they provide another level of allocation flexibility for the RIRs/LIRs.
Single subnet /64 Where it is known that only a single subnet can be used the user is assigned control of the interface ID part only
Single Device /128 Where it is known that only one device can be used the user is assigned a single interface ID

The justification for this, seemingly generous, address allocation policy is that the 45 address bits (48 bit global routing prefix - 3 bit binary prefix) still allow ~35 trillion /48 allocations (contrasted with the earth's population prediction of a mere 9 billion by 2050).

Experiment using the IPv6 Address Calculator.

IPv6 End-User Address Format

End-User addresses are assigned from the Global Unicast pool (current IANA IPv6 address block assignments). In addition a list of special assigments was created by RFC 4773. The IETF 6bone used a special range of 3FFe::/16 but the 6bone is disbanded and the address range has been returned to the IANA Reserved pool. The 128 bits breakdown as follows:

Global Routing Prefix (GRP) of 48 - 64 bits - assigned by IANA/RIR/LIR.
Name Size Description/Notes
reserved 3 bits 001 (or simply not 000 in some RFCs) - Global Unicast Address prefix (assigned by IANA)
- Variable Prior to RFC 4291 this field was 45 bits in length and for the global unicast address defined a strict hierarchy of Aggregators using the terms, TLA (Top Level Aggregator), sub-TLA and NLA (Next Level Aggregator). RFC 4291 obsoleted this structure and essentially leaves any sub format to Regional Internet Registries (RIRs). In addition the subnet ID field (previously defined to be 16 bits in length) is also defined to of variable length thus many of the current IPv6 specifications confusingly refer to the whole of this address space plus the subnet ID simply as the subnet ID to this field. IPv6 Global unicast address block assigments are maintained by IANA. The size of the IANA IPv6 address block assigment varies from /12 to /23.
80 - 64 bits - typically assigned by the user
Name Size Description/Notes
subnet ID 16 bits Used for subnet routing. See notes above. This field is formally (within RFC 4291) of variable length and while 16 bits is the normal allocation it can be - depending on the RIR policies - as low as 8 bits or 0 is the user only requires a single subnet.
interface ID (IID) 64 bits End User Interface (EUI-64). Equivalent to IPv4 host address - since this field alone is bigger that the whole IPv4 address space it is fairly generous! When used in stateless (SLAAC) configurations the EUI-64 address part may be created from the MAC as described below in Link Local. RFC 4941 defines a method by which temporary (pseudo random) addresses (EUI-64) may be created in order to create privacy (or anonymity).

IPv6 Configuration

IPv6 systems are typically multi-homed by default and have a link-local address configured by the host and may have a global unicast address which may be configured by one of four methods:

  1. Stateful - Statically assigned = manual configuration
  2. Stateful - DHCPv6 - Automatically assigned
  3. Stateless - Automatically assigned (SLAAC)
  4. Stateless - Automatically assigned (SLAAC) with DHCPv6 support for DNS information.

IPv6 Stateless Autoconfiguration (SLAAC)

IPv6 systems may be configured to provide global unicast addresses using Stateless Address AutoConfiguation (SLAAC - defined by RFC 4862) using what is called generically the Neighborhood Discovery Protocol (NDP). Stateless autoconfiguration requires a router to be present but not a DHCP server. The process of creating a stateless IPv6 address is as follows:

  1. Host sends a Router Solicitation message

  2. Host waits for a Router Advertisement message.

  3. Host takes top bits as defined in the Prefix Information of the Router Advertisement message and combines it with the 64 bit EUI-64 address (in the case of Ethernet this is created from the MAC address using this process) to create a Global Unicast address. The host also uses the source IP address - in the IP header - of the Router Advertisement (RA) message as its default gateway address. And since RFC 6106 can also obtain information about DNS service from the RA messages.

    RFC 4941 defines a method by which temporary (essentially pseudo-random from the interface derived EUI-64 address) addresses may be created in order to create privacy (or anonymity). RFC 4941 defines the default state of anonymous address creation as being off. If you wish anoymous access under IPv6 you may have to look for a specific configuration variable in your system to turn the anonymous feature on.

  4. Host then performs a Duplicate Address Detection (DAD) to ensure the address is unique (and on any of the anaonymous addresses generated by RFC 4941 procedures). If this check fails the host immediately aborts the autoconfiguration process and must be manually configured.

Example:

# Interface MAC
00-40-63-ca-9a-20
# IPv6 Interface ID (EUI-64)
# Note: bit 7 (U/L) set - see link local notes
::0240:63FF:FECA:9A20
# or
::240:63FF:FECA:9A20
# Prefix from Router Advertisement
2001:db8::/64
# global Unicast address
2001:db8::240:63FF:FECA:9A20

Notes:

  1. In stateless autoconfiguration (SLAAC) the global unicast (public address) and the default router address are configured automatically. Additional address information, such as DNS addresses, are not and must be provided by either DHCPv6 or manual configuration.

  2. When using SLAAC the low order 64 bits (EUI-64) of the Link Local and the Global Unicast address will be identical since both are created using the same process.

Up Arrow

Link-Local addresses are automatically assigned by the end user equipment and require no external configuration. Format defined by RFC 4291 Section 2.5.6. The address format uses a unique binary prefix (FE8::/10) and the remaining bits (118) are built from the local interface identifier. In the case of ethernet (RFC 2464) the MAC (48 bits) is used to create the EUI-64 value as shown below. Each physical layer supported has a separate RFC for example, FDDI, IEEE 802.15.4 etc. defining, among other things, how the link-local address is created. If an interface identifier has more than 118 bits the link-local address cannot be generated and the unit must be manually configured. Link-local addresses are not routable globally (outside the local LAN/network - however that is defined). The 128 bits of a link-local address for an ethernet interface breakdown as follows:

10 bits - Binary Prefix
Name Size Description/Notes
Binary Prefix 10 bits 1111 1110 10 or FE8::/10 Link-Local Prefix
118 bits - constructed from interface MAC
Name Size Description/Notes
- 54 bits all zeros
EUI-64 Contructed from the 48 bit MAC (802 LAN) or from a EUI-64 address(firewire etc.). Used both in Link-Local and SLAAC global unicast address construction
MAC 24 bits Top 24 bits of the 48 bit interface MAC. Vendor ID. Additionally, when created using the MAC address - or another EUI-48 derivation scheme - bit 7 (bits numbered from 1 in normal IETF convention) of this value is set to 1. Manually configured addresses do not set this bit thus both simplifying their generation and allowing external systems to identify how the address was generated. Note: This is the reverse of the meaning of this bit in the MAC address.
ID 16 bits Fixed value of FFFE inserted
MAC 24 bits low 24 bits of the 48 bit interface MAC. Serial number.

Example

# Interface MAC
00-40-63-ca-9a-20
# IPv6 Interface ID (EUI-64)

IPv6 Multicast Address Format

The Multicast format (which also replaces broadcast in IPv4) is defined by RFC 4291 Section 2.7. There is now a link-local multicast format defined by RFC 4489. The fomat of a global (non link-local) multicast address is defined below:

Bizarre: RFC 4291 supposedly defines the IPv6 address structure including multi-cast addresses (2.7), however both RFC 3306 and RFC 3956 (earlier RFCs) define a more detailed format (not reflected in RFC 4291) which have been used to update the table below. Very disconcerting.

Network Prefix 33 - 96 64 - "network prefix identifies the network prefix of the unicast subnet owning the multicast address. If P = 1, this field contains the unicast network prefix assigned to the domain owning, or allocating, the multicast address". Assumed to be a right aligned field (RFC silent on the matter), further assumed that if P = 0 field is not used (again RFC is silent on the matter).

IPv6 Link Local Multicast Address Format

As if this stuff was not already complicated RFC 4489 introduced the concept of a link-local (or link scoped) multicast format for situations where all configuration is stateless. Theoretically, routers (and other equipment) servicing a local (non-global) network could be now made self-configuring.

Name Bits Size Value Description/Notes
Binary Prefix 0 - 7 8 1111 1111 Fixed value a.k.a the routing prefix, binary prefix
flags 8-11 4 0RPT Flags have same meaning as defined for global multicast and must be set to 0011 meaning that T = 1 = "transient" group which has no IANA assignment and R = 1 = RP (Rendevous Point) encoded using method defined by RFC 3956.
scope 12-15 4 - Scope has the same meaning as defined for global multicast but can only take the values:
0 - reserved
1 - interface-local scope
2 - link-local scope
Reserved 16 - 23 8 - Reserved - must be 0
plen 24 - 31 8 - Fixed value of 1111 1111 denotes a link-local (or link scoped) multicast address
IID (EUI-64) 32 - 95 64 - Assigned using the normal link-local process depending on the media type.
Group ID 96 - 127 32 - Since the T bit is set this group ID is not defined by IANA though RFC 4489 does indicate that the guidelines for multicast address generation could be used (RFC 4489 and its position within the address also implies a mask of /96 applied to both the glocal and link-local format would yield a similar result.

IPv6 - IPv4 Interworking

IPv6 allows transport of IPv4 addresses using two methods. The methods are described in RFC 2893/RFC 4038 and RFC 4291 Section 2.5.5.

The first method is termed an "IPv4-compatible IPv6 address" and must use a globally unique IPv4 address. Please note: To avoid publication of a global IPv4 the example below shows a private (non-globally unique) IPv4 address purely to illustrate the principle:

# IPv4-compatible IPv6 address
# assume the host has an IPv4 address of:
192.168.0.5
# this is represented by the hex value C0A80005
# the IPv4-compatible IPv6 address would be
::C0A8:5
# or if you like writing zeros
0:0:0:0:0:0:C0A8:5
# or using the hybrid IPv6 - IPv4 notation
::192.168.0.5

The IPv4-compatible IPv6 address format is used when the end interface supports both IPv6 and IPv4 (a dual stack interface). This method is now deprecated (RFC 4291).

The second method is termed an "IPv4-mapped IPv6 address" and must use a globally unique IPv4 address. Please note: To avoid publication of a global IPv4 the example below shows a private (non-globally unique) IPv4 address purely to illustrate the principle:

# IPv4-mapped IPv6 address
# assume the host has an IPv4 address of:
192.168.0.5
# this address is represented by the hex value C0A80005
# the IPv4-mapped IPv6 address would be
::FFFF:C0A8:5
# or if you like writing zeros
0:0:0:0:0:FFFF:C0A8:5
# or using the hybrid IPv6 - IPv4 notation
::FFFF:192.168.0.5

The IPv4-mapped IPv6 address format is used when the end interface supports only IPv4 and indicates that a configured IPv6 system, for instance, a router or the IPv6 stack will have to perform conversion to the IPv4 protocol prior to communicating with the interface.

IPv6 over IPv4 Interworking

IPv6 over IPv4 (more commonly refered to these days as 6to4) allows two IPv6 networks/devices to communicate over an IPv4 network (defined by RFC 3056). Both ends of the network must have a globally unique IPv4 address and the end points must run either a 6to4 relay or a 6to4 transit service. A special unicast address block has been assigned for these classes of service (2002::/16). The IPv6 address format used by this address block is defined below

Name Bits Size Value Description/Notes
Unicast Prefix 0 - 15 16 2002::/16 IANA assigned value.
IPv4 Address 16 - 47 32 IPv4 Global Address IPv4 address associated with this 6to4 relay or transit service
subnet ID 48 - 63 16 - Normal usage
IID 64 - 1273 64 - Interface ID (EUI-64)

The low order 80 bits allow for end user transparency within the IPv6 address. The relay or transit service will extract the IPv4 address when communicating accross the IPv4 cloud.

Note: Another IPv4 to IPv6 transition method is biting the dust. RFC 7526 deprecates the reserved Unicast prefix (2002::/16) used in 6to4 tunneling. For backward compability the feature will still exist but for new implementations: forget it. Meh.

IPv6 Address Calculator

IPv6 Calculator: Enter an IPv6 address with its /Prefix (or slash) notation in the IPv6/Prefix: box and click IPv6 Info. The calculator will fully expand the IPv6 address and place in IPv6 Expanded:, IPv6 Netmask in compressed format, IPv6 GPR contains the top part or the address which may be the Global Routing Prefix (GRP) or not depending on the /Prefix value and IPv6 User: is the lower part of the address based on the /Prefix value. Finally, the reverse map zone name of the IPv6 address is calculated based on the /Prefix value (IPv6 addresses below this name will be defined in the reverse zone file) and shown in FQDN format in Reverse Zone. In Zone IPv6: shows the IPv6 address element that would appear with the zone file based on the /Prefix value. Since IPv6 addresses cover very serious numbers the No. of IPs: box is only used in the alternative mode described below and is only updated in that context.

Alternatively, enter a single IPv6 address (that lies anywhere in the desired range) without the /prefix in IPv6/Prefix and the number of desired IP addresses (if it is not a power of 2 it will be rounded up to the nearest power of 2 - a maximum of 6 digits is allowed) in No. of IPs then click IPv6 Info. The calculator will populate IPv6/Prefix (with the calculated /Prefix to cover the required or calculated number of IP addresses), No. of IPs will be updated if needed (due to any power of 2 rounding required) and IPv6 Netmask, IPv6 GPR, IPv6 User:, Reverse Zone and In Zone IPv6: will be populated normally.

The Clear button zaps ALL entries in IPv6 Calculator only.

Notes:

  1. Validation and other errors are shown in the IPv6 Netmask box for no very good reason.

  2. When entering a /prefix IPv6 address you only need to enter as many colon elements as are required by the /prefix (more is not a problem), if you enter less than the required number the calculator silently pads to the right with zeros.

  3. While a /Prefix for IPv6 is most normally a multiple of 8 (or even 16) the calculator allows any bit value. You can break on very strange boundaries if desired.

  4. The calculator follows the recommendation of RFC 5952 about use of lower case hexadecimal characters, removal of all leading zeros in address elements, largest zero block elimination but it will eliminate a single zero block if this is the only one available (since this obeys the longest zero block elimination rule).

  5. The calculator accepts IPv6 addresses in IPv4-Mapped IPv6 format (x:x:x:x:x:x:d.d.d.d) but does not verify that the required selectors are present. You currently have to do some work.

IPv6/Prefix: No. of IPs:
IPv6 Expanded:
IPv6 Netmask:
IPv6 GPR:
IPv6 User:
Reverse zone:
In Zone IPv6:

  1. Javascript implementations may vary from browser to browser. This feature was tested with MSIE 10, Gecko (Firefox 25.0.1), Opera 11.10 and Chrome (31.0.1650.57 m) - so will likely work with any WebKit based browser, which obviously includes Safari (and now even Opera!)). If the tester does not work for you we are very, very sad - but yell at your browser supplier not us. However, if you do think you have found, or want to suggest improvements, an error please take the time to email using the link at the foot of this page.

IPv6 Frame Format

IPv6 headers are daisy chained. The Next Header field - present in every header except the upper layer header - indicates which header comes next as shown in the diagram below:

IPv6 Daisy chained headers

Notes:

  1. Zero or more Extension headers may be present.

  2. Multiple Extension headers of any type may be present.

  3. All Extension headers are assumed to be of variable length and contain a length value (expressed in multiples of 8 octets).

  4. Only one upper layer header may be present and is unchanged from IPv4 e.g. tcp with the exception of the format of the 'pseudo-header' used to generate the checksum.

  5. Data (MTU) length is defined to be a minimum of 1280 octets with a recommendation of 1500+ octets. If any routing link cannot carry this size of MTU, link specific fragmentation must be carried out below (i.e. invisible to) IPv6.

  6. When carrying UDP traffic in the upper layers the optional (in IPv4) UDP checksum MUST be present.

  7. The pseudo header used in TCP, UDP and IPv6 ICMP is assumed be a 40 octet field and have the following format:

    Name Size Description/Notes
    Source 128 bits IPv6 source address
    Destination 128 bits IPv6 destination address
    Packet Length 32 bits Length in octets of the upper layer data packet plus associated header.
    - 24 bits Must be zeros
    Next Header 8 bits Assumed to contain the value of the protocol carried in the upper layer e.g. 6 = TCP etc..

IPv6 Header Format
Name Length Description/Notes
version 4 bits value = 6. Same location as IPv4 - everything after this changes.
traffic class 8 bits None formally defined with IANA (late 2004). When used with Explicit Congestion Notification (ECN) (RFC 3168) may take values defined here and here.
Flow Label 20 bits -
payload length 16 bits unsigned length in octets of payload (excludes header but includes extensions)
next header 8 bits Identifier in following header - same values as IPv4 Protocol field Some common values:
0 (0x00) IPv6 Hop-by-Hop Option
1 (0x01) ICMP protocol
2 (0x02) IGMP protocol
4 (0x04) IP over IP
6 (0x06) TCP protocol
17 (0x11) UDP protocol
41 (0x29) IPv6 protocol
58 (0x3A) IPv6 ICMP protocol
59 (0x3B) IPv6 No Next Header (terminates a no upper layer frame)
Definitive list is here
hop limit 8 bits Maximum number of hops. Formalises the current practice when using the TTL in IPv4.
source IP 128 bits -
destination IP 128 bits -

Order of Headers

Where multiple headers are present the recommended sender order is (but the receiver must accept in any order):

IPv6 Header
Hop-by-Hop Header
Destination Options
Routing Headers
Fragment Headers
Authentication Headers
Encapsulation Security Payload (ESP) Header
Destination Options
Upper Layer Header + data

Up Arrow

Extension Headers

Extension headers are always multiples of 8 octets. To allow skipping and processing of extension headers they all begin with the following 16 bit stub format:

IPv6 Extension Header - Stub format
Name Length Description/Notes
Next Header 8 bits Same values as IPv6 Next Header
Extension Hdr Len 8 bits Unsigned integer. The total length of the extension header in multiples of 8 octets, excluding the first 8 octets e.g. a value of 0 = 8 octet header length, value = 2 = 24 octet header length etc. NB the length field in ICMPv6 does not use this convention - it's always good to have consistency in standards.

Up Arrow

Header Options

The Hop-By-Hop and Destination Headers carry a variable number of options within the header and use a classic TLD (or TLV in the standards paralance) format as shown below:

Name Length Description/Notes
Type 8 bits The two high order (or low order depending on your numbering convention) bits indicate what action to take if the option is not recognized and may take one of the following values: 00 = skip option - keep processing
01 = discard packet
10 = discard packet and send ICMPv6 Parameter Problem (Code 2) message
11 = discard packet and, if not Multicast address, send ICMPv6 Parameter Problem (Code 2) message
The third high order bit indicates whether the option can change before reaching its destination 0 = data will not change, 1 = data may change. If the bit is set and an Authentication Header is present then an all zero option value must be assumed when computing any digest.
Length 8 bits Length in octets of the option data - does not include the type or length value.
Data variable Depends on Type

In order to force so-called natural alignment of option fields two padding options are provided. An Option Type of 0 indicates a 1 octet pad (and does not have associated length or data fields), a standard Option with a Type of 1 allows for multiple octet padding. NB in this case a 2 octet pad will have an Option Length of 0.

IPv6 RFCs

This rather daunting list of RFCs describe IPv6 or are relevant to it. Many of the later RFCs simply roll-back features of the earlier ones. Most of the new work is associated with mobile development and various tunneling methods.

Note: The main repository for RFCs is maintained by the IETF, text versions (the normative reference) may be viewed at www.ietf.org/rfc/rfcXXXX.txt or www.rfc-editor.org/rfc/rfcXXXX.txt (where XXXX is the 4 digit RFC number - left padded with zeros as necessary). Currently published RFCs are pointed to https://www.rfc-editor.org/info/rfcXXXX (where XXXX is the 4 digit RFC number - left padded with zeros as necessary) which contains various information and links to the text (normative) reference and a PDF (non-normative) version. The RFC may also be viewed at http://datatracker.ietf.org/doc/rfcXXXX/ (where XXXX is the 4 digit RFC number - left padded with zeros as necessary) which also contains various RFC status information together with a list of alternative formats, such as, text, PDF and HTML (this is the working area version of the document). Finally, there is now a searchable RFC list.

<ingrained habit> The RFC links below yield a plain text version which was copied to our site when the RFC was issued. We started this service a long time ago when the world was young, RFCs were maintained in some strange places, occasionally moved location, and performance and reliability of the repositories was very variable (being generous). None of these conditions apply today, far from it. Nevertheless, we persist in our ingrained habits for no particularly good reason (old dog...new tricks..). If you want/prefer/need more choice you are advised to use one of the links identified above, if, however, you just want to read the blasted RFC, feel free to click the links below.</ingrained habit>
