What is the MAC Address?

A media access control address (MAC 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. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.

MAC addresses are most often 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 (not to be confused with a memory physical address). This can be contrasted to a programmed address, where the host device issues commands to the NIC to use an arbitrary address.


What is the MAC Address Type?

  • MA-L: IEEE MAC Address Large (24-bit block size)

  • MA-S: IEEE MAC Address Small (36-bit block size)
  • OUI24: Organizationally Unique Identifier (24-bit block size)
  • OUI36: Organizationally Unique Identifier (36-bit block size)
  • IAB: Individual Address Blocks (36-bit block size)
  • CID: Company ID Blocks (24-bit block size)
  • EUI48: Extended Unique Identifier (48-bit block size)
