CoachA multicast group is an IPv4 address between 224.0.0.0 and 239.255.255.255 that names a set of receivers rather than one host: a datagram sent to it is delivered to every member. The Internet Group Management Protocol (IGMP) is the protocol by which a host tells its neighbouring routers which groups it wants to receive, and, in version 3, from which sources.
