The MAC (Media Access Control) address is a 12 digit unique code assigned to network devices. Think of it like a serial number, no two devices will have the same MAC address. The address is hard coded into the devices memory / firmware, it may also be on a sticker on the device.
MAC Address Format
MM:MM:MM:SS:SS:SS format.
Example MAC Address :

( 20-47-47 identifies the manufacturer as a Dell and the D4-A9-72 is the unique serial number )
The first 3 (MM) are the ID number of the manufacturer, which is assigned by an Internet standards body.
The second 3 (SS) are the serial number assigned by the manufacturer.
