When I say ip net, I mean ip subnet, which is what you're referring to with "255.255.255.0".
It's not about searching in their respective space either. Arp is a broadcast, broadcasts happen ip subnet wide just like DHCP requests. Routers which provide connectivity between ip subnets don't pass broadcasts. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
