A media access control address, MAC is a unique identifier which is assigned to network
interfaces for communications on the physical network segment. MAC addresses are used as a
network address for most IEEE 802 network technologies, including Ethernet and WiFi.

MAC addresses are assigned by the manufacturer of a network interface controller (NIC) and
are stored in its hardware, such as the card’s read-only memory or some other firmware
mechanism. If assigned by the manufacturer, a MAC address usually encodes the
manufacturer’s registered identification number and may be referred to as the burned-in
address (BIA). It may also be known as an Ethernet hardware address (EHA), hardware
address or physical address.
