If anyone knows : where I could read more about this could you please post. Maybe a FAQ or : RFC??? Thanks : --- Jared : --jared@vt.edu This is significantly brain damaged. If the kernel got a packet, how would it resolve which device to route the packet to? While I'm not sure how it is actually implemented, my only guess is that in order to have two devices with the same IP address, the resolution would have to be done with some sort of case statement. Wow, that's pretty obnoxious if you had some heavy duty network happening. It makes more sense to disallow same IP on more than one device. But that's just me. -- Giao Nguyen Computer Science Student Will program for food
