The Media Access Control, or MAC address, is an alphanumeric code assigned to certain types of networking hardware. The MAC address is typically assigned to a piece of hardware by its manufacturer, and they are commonly assigned to Ethernet cards.

Knowing each MAC address on a network can help the network administrator easily identify and filter intruders.
