A MAC address can be compared to your name and the network address to your mailing address. For example, if you were to move to another town, your name would remain unchanged, but your mailing address would indicate your new location. Network devices (routers as well as individual computers) have both a MAC address and a protocol (network layer) address. When you physically move a computer to a different network, the computer maintains the same MAC address, but you must assign it a new network address.
