What is a MAC address? What is OUI? What are MA-L, MA-M, MA-S?

A MAC address is a unique identifier for network interfaces. It is a 48-bit number (12 hexadecimal characters). They can either be written in either of these formats:

  • MM:MM:MM:SS:SS:SS
  • MM-MM-MM-SS-SS-SS

An OUI {Organizationally Unique Identifier} is a 24-bit number that uniquely identifies a vendor or manufacturer. They are purchased and assigned by the IEEE. The OUI is basically the first three octets of a MAC address. For example, these are examples of OUI:

  • 00:00:0A -- this is owned by Omron
  • 00-0D-4B -- this is owned by Roku, LLC

MA-L, or MAC Address Block Large is a block of MAC addresses where the maximum number of addresses is 224 or 16 million. MA-L was previously known as OUI.

MA-M, or MAC Address Block Medium, is a block of MAC addresses where the maximum number of addresses is 220 or 1 million.

MA-S, or MAC Address Block Small, is a block of MAC addresses where the maximum of addresses is 212 or 4096. MA-S was previously known as OUI-36. IAB is also known as Individual Address Blocks and the number of addresses is 224 or 16 million.
