ICMPv6 Router Renumbering Messages
One of the more interesting decisions made in IPv6 was the selection of a very large 128-bit address size. This provides an address space far larger than what humans are ever likely to need, and probably larger than needed for IPv6, strictly speaking. What this wealth of bits provides is the flexibility to assign meaning to different bits in the address structure. This, in turn, serves as the basis for important features such as the autoconfiguration and automated renumbering of IPv6 addresses.
IPv6 Router Renumbering
The renumbering feature in IPv6 is of particular interest to network administrators, since it has the potential to make large network migrations and merges much simpler. In August 2000, the IETF published ...
