Find the MAC Address

A MAC (Media Access Control) address, sometimes referred to as a hardware or physical address, is a unique, 12-character alphanumeric attribute that is used to identify individual electronic devices on a network. An example of a MAC address is: 00-B0-D0-63-C2-26.

Note: Many devices have multiple MAC addresses, so consider your device and whether you'll be connecting via an ethernet cable (wired) or over a wi-fi network (wireless) before selecting yours.
