MAC Address

A MAC address (“media access control address”) of a computer is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and Wi-Fi. MAC addresses are typically represented as a string of six pairs of hexadecimal digits separated by dashes (“-”) or colons (“:”), such as “00-11-D9-36-53-E5”. Even though insecure, MAC addresses are often used as Computer IDs by legacy licensing platforms.
