Ok, some type of use like that would make sense. But it's still bad marketing to "sell 8, but you can only use 5." It should be, "sell 5, plus you get 3 nifty special-function IP addresses at no extra charge!" I understand the broadcast address (send to broadcast, your 5 IP's get the traffic), and I think I see why a gateway address could be needed in your same subnet (if the IP isn't in your local /29 subnet, then send it to the gateway IP, guaranteed to be on the same ethernet link for routing). Could you explain the "network address" concept to me? I don't get that one. ~ Nathan -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
