How  to broadcast a message on the Internet? Two questions need to be  answered: What address should be used as the broadcast address. How to  send data to the broadcast address? A broadcast address is the subnet’s  network number with all onebits set for the host portion of the address.  For instance, if a network IP address is 192.168.1.0, and the netmask  is 255.255.255.0, the last byte of the address is the host number  (because the first three bytes, according to the netmask, correspond to  the network number). So the broadcast address is 192.168.1.255. Under  Unix, the ifconfig command will actually give you all this information.
