will UtpClient.JoinMulticastGroup() work in LAN without router?

So for a UtpClient to JoinMulticastGroup, there must be a router in the
network and with multicast enabled?

That is, for a small LAN with a few computers connected by a hub or siwtch,
it won't work, right?

It will work but you have to be concerned with flooding the network.
A multicast enabled switch will only send the multicast data to the
clients which joined the specific multicast group. A standard switch
or hub will send the data to every device on the network.

So if the network really is small and you're sending a small amount of
multicast data, then it should work without major problems, but I
wouldn't really recommend it.

HTH,
