What Is a MAC Address?

A MAC (Media Access Control) address is a unique 48-bit hardware identifier assigned to network interfaces (NICs, Wi-Fi cards, Bluetooth adapters, etc.). It operates at Layer 2 and is used for communication within the same local network.

MAC Address Structure

  • 48 bits — 6 bytes / 12 hexadecimal digits
  • Common formats: 00:1A:2B:3C:4D:5E or 00-1A-2B-3C-4D-5E
  • First 24 bits → OUI — identifies the manufacturer
  • Last 24 bits → Device-specific, assigned by the manufacturer
  • Managed and assigned by the IEEE Registration Authority

IEEE Block Types

  • MA-L — 24-bit prefix, ~16.8 million addresses. Classic OUI for large organizations.
  • MA-M — 28-bit prefix, ~1 million addresses. Medium-sized vendors.
  • MA-S — 36-bit prefix, 4,096 addresses. Small vendors & IoT devices.
  • CID — Company ID, 24-bit identifier used for non-MAC protocol contexts.
  • IAB — Legacy (inactive since 2014), replaced by MA-S.
