Multicast is used to distribute data from one source to many receivers.These receivers normally are executing an application which in its underlying logic has joined a multicast group which is essentially a ip address that is able represent multiple nodes on a network. Public multicast ip addresses are rarely available to network managers or application dev teams hence applications should be developed to accept multicast ip address and port information in its initializtion code. This approach allows an application to be ip address agnostic and and allows the app to join any available multicast address
