IPv6 Anycast Addresses
Following are some of the required Internet Protocol V6 anycast addresses that might help you up to some extent.
Anycast addresses can be found on the internet on different web sites but most probably you can find them is unicast address space.
Subnet-Router Anycast Address
[RFC2373] the numbers in the square brackets define the Subnet-Router Anycast Address. To make you understand it, its format is as follows:
| n bits | 128-n bits |
+------------------------------------------------+----------------+
| Subnet prefix | 00000000000000 |
+------------------------------------------------+----------------+
The "subnet prefix" in the figure describes the anycast address of the location and is the starting which identifies a special link by the zeros written. The one anycast address written here is syntactically same as the unicast address would be for an interface on the link with the interface recognition set to zero.
All the data packets that are sent to the Subnet-Router at the anycast address will be posted to one and only one router on the subnet. All the routers are needed to hold the subnet-Router anycast addresses for the subnets to which they are connected to any interface.
Reserved Subnet Anycast Addresses
[RFC2526] the numbers in the Square brackets define a set of special subnet anycast addresses that are created and held for additional addresses. The values present here are the biggest 128 values that can be within a subnet. The important rules and the correct syntax is defined by the numbers written in the brackets and the description below [RFC2526].
The present IPv6 subnet anycast identifiers are as follows:
Decimal Hexadecimal Description for subnet Reference to the sub net
-------- ----------- --------------------------------- ---------
127 0x7F Reserved
126 0x7E Mobile IPv6 Home-Agents anycast [RFC2526]
0 0x00 Reserved
All IPv6 reserved subnet anycast identifiers not listed above are reserved.
