Multicast (point-to-multipoint) is a communication feature that allows a
source host to send a message to a group of destination hosts.
Multicasting reduces traffic on the local network by sending only one
(multicast) packet out to a higher-bandwidth relay point.
Multicasting differs from broadcasting in that a receiver must join a
multicast group in order to receive group messages. Each multicast group
has its own group address, which is a Class D IP address—224.0.0.0—
239.255.255.255.
