When I ping the broadcast address of my LAN I get an ICMP message as "Request timed out". Why don't I get reply from every computer on LAN?
Good question. I think I may have found the answer. It turns out, IP implementations only need *optionally* respond to broadcast pings. MS has chosen not to allow windows machines to reply to such pings - probably for security reasons. Other vendors might allow the IP stacks to reply to broadcast pings - I know some of my IOS equipment replies to them.
