Executive Summary

There are three fundamental types of IPv4 addresses: unicast, broadcast, and multicast. A unicast address is designed to transmit a packet to a single destination. A broadcast address is used to send a datagram to an entire sub network. A multicast address is designed to enable the delivery of datagram to a set of hosts that have been configured as members of a multicast group in various scattered sub networks. Multicasting is not connection oriented. A multicast datagram is delivered to destination group members with the same "Best-effort" reliability as a standard unicast IP datagram.
