MAC Address
Media Access Control (MAC) address is the hard-coded address on the network interface controller (NIC) of the Physical layer node attached to the network.
Each MAC address must be unique and follow this format:
- It must consist of 48 bits.
- It must be displayed by 12 hexadecimal digits (0-9, A-F).
- The first 6 hexadecimal digits in the address is a vendor code or organizationally unique identifier (OUI) assigned by the NIC manufacturer.
This is an example of a MAC address: 00:00:07:A9:B2:EB
