When running multiple logical subnets on the same physical network, the following command can be used to tell IP to treat all subnets as local and to use ARP directly for the destination:
route add 0.0.0.0 MASK 0.0.0.0 <my local ip address>
Thus, packets destined for non-local subnets are transmitted directly onto the local media instead of being sent to a router. In essence, the local interface card can be designated as the default gateway. This can be useful where several class C networks are used on one physical network with no router to the outside world, or in a proxy-ARP environment
