Anycast is a network addressing and routing methodology in which a single IP address is shared by devices (generally servers) in multiple locations. Routers direct packets addressed to this destination to the location nearest the sender, using their normal decision-making algorithms, typically the lowest number of BGP network hops. Anycast routing is widely used by content delivery networks such as web and name servers, to bring their content closer to end users.

==History== The first documented use of anycast routing for topological load-balancing of Internet-connected services was in 1989; the technique was first formally documented in the IETF four years later. It was first applied to critical infrastructure in 2001 with the anycasting of the I-root nameserver.
