How Do I Find All IP & MAC Addresses on a Router?

• Answer:

  Most routers have two or more physical interfaces that serve as connection points to different networks. In addition, routers may also be configured with virtual interfaces. Both types of interfaces may have IP addresses assigned to them. In some instances, unique MAC addresses may be assigned to the interfaces as well.
