In fact, using alias techniques, you can assign multiple addresses to the same interface. This is how virtual domains are done. A router will have a seperate (could be more than one) IP address for each ethernet card installed. If you only have one interface, then it's not a router it's a host. A router, often called a gateway but not to be confused with a bridge, is necessary to enable hosts on different subnets to talk. -Craig
