What are MAC addresses?

A MAC address is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, IEEE 802 standards use 48 bites or 6 bytes to represent a MAC address. This format gives 281,474,976,710,656 possible unique MAC addresses.

IEEE 802 standards define 3 commonly used formats to print a MAC address in hexadecimal digits:

• Six groups of two hexadecimal digits separated by hyphens (-), like 01-23-45-67-89-ab
• Six groups of two hexadecimal digits separated by colons (:), like 01:23:45:67:89:ab
• Three groups of four hexadecimal digits separated by dots (.), like 0123.4567.89ab
