MA-M, or MAC Address Block Medium, is a block of MAC addresses where the maximum number of addresses is 2 20 or 1 million. MA-L, or MAC Address Block Large is a block of MAC addresses where the maximum number of addresses is 2 24 or 16 million. The OUI is basically the first three octets of a MAC address. They are purchased and assigned by the IEEE. They can either be written in either of these formats:Īn OUI is a 24-bit number that uniquely identifies a vendor or manufacturer. It is a 48-bit number (12 hexadecimal characters). What is a MAC address? What is OUI? What are MA-L, MA-M, MA-S?Ī MAC address is a unique identifier for network interfaces.
