Any-Source Multicast

Any-Source Multicast is the IP multicast service model defined in RFC 1112, host extensions for IP Multicasting. An IP datagram is transmitted to a host group which is a set of zeros and is identified by a single IP destination address (224.0.0.0 through 239.255.255.255 for IPv4). End hosts are able to join or leave a group any time as there is no restriction to the location or number. This model supports multicast groups with a number of senders. Any end host can be transmitted to a host group even if it is not a member of that group.
