A MAC address is a unique address number given to each computer or network device on a computer network and formatted in hexadecimal format.
MAC addresses are most frequently assigned by the firm of a network interface controller (NIC) and are stored in its hardware, such as the card’s ROM (Read Only Memory) or some other firmware system.
MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64. The IEEE claims trademarks on the names EUI-48 and EUI-64, in which EUI is an abbreviation for Extended Unique Identifier.
