anycast

Communication that takes place over a network between a single sender and the nearest of a group of receivers.

Anycast is used in IPv6 as a method of updating routing tables. One host initiates an update of a router table for a group of hosts, sending the data to the nearest host. That host then sends the message on to its nearest router until all the routing tables in that group are updated.

Compare with multicast and unicast.
