MAC Address Overview A Media Access Control address (MAC address) is a hardware identifier that uniquely shows each device on a network. Primarily, the manufacturer assigns it. They are often found on a device’s network interface controller (NIC) card. A MAC address can also be referred to as a burned-in address, Ethernet hardware address, hardware address, or physical address. A MAC address is a 48-bit hexadecimal address. It is usually six sets of two digits or characters, separated by colons. An example MAC address would be 00:00:5e:00:53:af. Many network cards and other hardware manufacturers use a unique sequence at the beginning of their products’ MAC addresses. This is called an organizationally unique identifier (OUI). The OUI is usually the first three bytes of digits or characters. The IEEE (Institute of Electrical and Electronics Engineers) administers manufacturers’ OUIs. 373
