Find the MAC Address of a Computer
A MAC address is also known as a hardware address or an Ethernet address. It is a unique identifier specific to the network card in the computer. A MAC address is usually shown in this form: XX-XX-XX-XX-XX-XX, where each X is a digit or letter from A to F. To find the MAC address of a computer on your network:
- From the command line of the computer whose MAC address you want to find, type ipconfig /all (Windows) or ifconfig (OS X or Linux).
- Look for the entry for the computer’s “physical address.” This value is the MAC or hardware address for the computer.
