Multicast Address

It is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (Layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (Layer 3 for OSI) for Internet Protocol Version 4 ([p2p type=”slug” value=”ip-addressing-scheme-ipv4″]IPv4[/p2p]) or Version 6 (IPv6) multicast.
