    MAC - Media Access Control Address

    A media access control address (MAC address) is a unique identifier number for an Ethernet or network adaptor over a network. It is used as a network address for most IEEE 802 network technologies, including EthernetWi-Fi, and Bluetooth. In the Open SystemsInterconnection (OSI) model, MAC addresses are used in the medium access control protocol sub-layer of the data link layer.


    Data Link Layer is divided into two sub-layers –
    • Logical Link Control(LLC) Sublayer
    • Media Access Control(MAC) Sublayer

    MAC Address is also known as Physical Address of a network device.

    For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e.

    Each MAC address consists of a 12-digit hexadecimal notation.

    The Format of a MAC Address

    • MM:MM:MM:SS:SS:SS
    • MM-MM-MM-SS-SS-SS
    • MMM.MMM.SSS.SSS

    The leftmost 6 digits (24 bits) called a "prefix" is associated with the adapter manufacturer.
