About MAC Addresses

A MAC (Media Access Control) address is a unique identifier assigned to network interfaces. It consists of 6 octets (48 bits) represented in hexadecimal.

  • First 3 octets = OUI (Organizationally Unique Identifier) — identifies the vendor
  • Last 3 octets = NIC-specific (assigned by the manufacturer)
  • Bit 0 of first octet = I/G flag: 0 = Unicast, 1 = Multicast
  • Bit 1 of first octet = U/L flag: 0 = Universal, 1 = Locally Administered
