MAC address is the 48-bit address, which is labeled on your system NIC (Network Interface Card). MAC address depends on the number of NIC cards. If your system has one NIC card, then your system has one MAC address; similarly, if your system has three NIC cards, then your system has three MAC addresses.

The first three pairs are called OUI (Organizational Unique Identifier). Every organization has its own unique OUI for all of its products. For Example, “The first three pairs of all HP products must be the same” in the same way the first three digits of all DELL products also must be the same.

The second portion is called NIC (Network Interface Controller), which is specific. It cannot be duplicated for other products; for example, if one HP laptop has NIC portion “00-EA-A3” then this address can never be used for other HP laptops.
