This command-line tool can be used to send multicast packets or to listen for packets being sent to a multicast group address.
Mcast is useful for testing whether or not there is multicast connectivity between two computers on your network. This can be done by using Mcast to send packets from one of the computers on your network to the group address you wish to test. On the computer for which you want to test connectivity, you can use Mcast to listen for packets received on the group address. Using this method, you can determine whether or not there is multicast connectivity between the two computers.
Multicasting is a method of point-to-multipoint delivery of information over a network. In contrast to sending multiple packets to multiple unicast addresses, this method sends all information in a single packet and requires no overhead for keeping lists of recipients. And unlike broadcast packets, multicast traffic does not disturb those nodes that are not listening for it. Multicast-capable routers can forward the multicast packet to all networks where there is at least one node listening.
