Answer
A MAC address is a 6-byte address with each byte separated by a colon. The first three bytes (24 bits) of MAC address are the manufacturer-id or the Organisational Unique Identifier (OUI) (assigned to manufacturer by IEEE) and the last three bytes (24 bits) are the card-number (assigned by manufacturer). For example, a sample MAC address could be: 10 : B5 : 03 : 63 : 2E : FC. Here, 10 : B5 : 03 is the manufacturer-id and 63 : 2E : FC is the card number assigned by the manufacturer.
