How to identify a broadcasted message?
<p>Sometimes I have to send a message to a specific IP and sometimes I have to broadcast the message to all the IP's in my network. At the other end I have to distinguish between a broadcast and a normal one, but <code>recvfrom()</code> just returns the address the message came from;
there is no difference between them. Can anyone help me distinguish them?</p>

<p>UDP is the protocol.</p>
