Unicast is communication
between a single sender and a single receiver over a network. The term exists
in contradistinction to multicast,
communication between a single sender and multiple receivers, and anycast, communication between any sender and the nearest of a
group of receivers in a network. An earlier term, point-to-point
communication, is similar in meaning to unicast. The new Internet Protocol
version 6 (IPv6) supports unicast as well as
anycast and multicast.
