IPv6 Essentials

3.11. Required Addresses

The standard specifies that each host must assign the following addresses to identify itself:

• Its link-local address for each interface

• Any assigned unicast and anycast addresses

• The loopback address

• The all-nodes multicast address

• Solicited-node multicast address for each of its assigned unicast and anycast addresses

• Multicast addresses of all other groups to which the host belongs

A router needs to recognize all of the previous address, plus the following:

• The subnet-router anycast address for the interfaces for which it is configured to act as a router on each link

• All anycast addresses with which the router has been configured

• The all-routers multicast address

• Multicast addresses of all other groups to which the router belongs
