anycast

A technique for updating routing tables in IPv6, the next generation of IP addressing. Anycast sends a message to the nearest router within a group. That router in turn sends it to its nearest router. Starting in 2003, additional root servers on the Internet were replicated using the Anycast method. See IPv6 and root server.

While there are plans for aggressive aggregation to reduce table entries, the requirement for both provider based and geographical addresses, the need for connections to multiple ISPs, plans to connect control devices on the Net, and the use of features like Anycast [Deering and Hinden 1995], all make it unlikely that backbone prefix tables will be smaller than in IPv4.
