• A unicast IP address is an IP address that identifies a unique host on a network.
• A multicast IP address is an IP address that is capable of sending packets to a selected group of hosts, known as a multicast group.
• A broadcast IP address is an IP address that is capable of sending packets to all the hosts on a network.
