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:
1. From the command line of the computer whose MAC address you want to find, type
ipconfig /all
(Windows) or ifconfig (OS X or Linux).
2. Look for the entry for the computer’s physical address. This value is the MAC or hardware address for
the computer.
