    It's a theoreticaly unique number associated with your network card. In theory no other network card should have that mac address.

    The MAC address is a unique value associated with a network adapter.
    MAC addresses are 12-digit hexadecimal numbers (48 bits in length).
    MAC addresses are usually written in one of the following two formats:

    MM:MM:MM:SS:SS:SS
    MM-MM-MM-SS-SS-SS

    The first half of a MAC address contains the ID number of the adapter manufacturer.
    The second half of a MAC address represents the serial number assigned to the adapter by the manufacturer.
