Receiving Unicast packets on Multicast socket

[Rich DeMarinis]

Is it possible to have a single MulticastSocket also receive Unicast
packets in Java? I'm able to bind one of each socket to the same port
but I'd like to be able to use just one socket. I'm running under
RedHat 9.0.

Thanks,
Rich

Yes, since your application uses the same port number for unicast and
multicast datagrams.

MulticastSocket is a subclass of DatagramSocket, so it can receive
unicast datagrams. This is regardless of any multicast groups it has
joined, however it will only receive datagrams (of either kind) sent
to the bound port.
