The Address Resolution Protocol (ARP) is a handy little networking utility that you can use to find the MAC address of another computer on your network. Before you can communicate with another computer on the network, the computer name must be resolved to an IP address. Then the IP address must be resolved to the MAC address or physical address. This is done using ARP. Your computer will keep a physical address translation table.

If you want to determine the MAC address of another computer, simply ping the computer by opening the command prompt and typing ping followed by the IP address assigned to the remote computer. Since the IP address has to be resolved to the MAC address, an entry will be added to you physical address translation table. At the command prompt type arp -a. The results will display the IP address and the MAC address of the remote computer.
