UDP broadcasting

[Guest]

in UDP broadcasting, how do i know from which client was the message sent to
the server? is there a way to know this without having to place the IP of the
sender in the message itself? Thank you so much in advance!

Yes...when the UDP datagram is received, you use a "ReceiveFrom" method,
which returns the endpoint address for the sender.

The sender may or may not even know its actual IP address, so including the
sender's address in the datagram isn't a very reliable method anyway. It is
much better for the receipient to inspect the address as reported to it from
the receiving method.
