Every network card manufacturer gets a universally unique 3-byte code called the Organizationally Unique Identifier (OUI). Manufacturers agree to give all NICs a MAC address that begins with the assigned OUI. MAC addresses are 6 Bytes (48 bits) long. Every Ethernet network interface card (NIC) has a MAC address burned in its firmware, which is why MAC addresses are sometimes known as hardware addresses. Ethernet uses MAC (Media Access Control) addresses to uniquely identify a host in an Ethernet environment.
