A Media Access Control (MAC) address is a unique identifier assigned to a Network Interface Controller (NIC). It serves as a hardware address for communication within a network segment.
The first 24 bits (3 bytes) of a MAC address are known as the Organizationally Unique Identifier (OUI). These are assigned by the IEEE to specific vendors to ensure global uniqueness.
