I seem to remember reading somewhere that in the original implementations of IP xxx.xxx.xxx.0 was a broadcast address. I think the early BSD's worked this way. Sometime or another everyone decided to use xxx.xxx.xxx.255, but I guess some IP stacks still support both.?. I wish I could remember where I read this so that I could provide a pointer. TCP/IP Illustrated V2. has a small blurb about accepting an IP address of all 1's or all 0's as a broadcast, but it doesn't go into any detail or supply any historical context. -- --- Nathan Valentine - [EMAIL PROTECTED] University of Kentucky Distributed Computing Systems Lab AIM: NRVesKY ICQ: 39023424
