IP Multicasting Overview. The concept of group membership is central to IP multicasting. IP multicast datagrams are sent to a group, and only members of the group receive the datagrams.A group is identified by a single IP multicast address, which is an IP address in the Class D range of 224.0.0.0 to 239.255.255.255 (designated as 224.0.0.0/4 in classless interdomain routing (CIDR) notation).These Class D addresses are known as group addresses.n this illustration, the hosts and routers are multicast-enabled so that the following can occur: 1  The sending host sends multicast datagrams to a designated group address. 2  The routers forward the multicast datagrams to any network segments that include group members.
