An MA-L (MAC Address Block Large) assignment includes an OUI and large blocks of EUI-48 and EUI-64 values which can be used as MAC Addresses, Bluetooth Device Addresses, Ethernet Addresses or object identifiers.
MA-M
An MA-M (MAC Address Block Medium) assignment includes medium blocks of EUI-48 and EUI-64 values which can be used as MAC Addresses, Bluetooth Device Addresses, Ethernet Addresses or object identifiers.
MA-S
An MA-S (MAC Address Block Small) assignment includes an OUI-36 and small blocks of EUI-48 and EUI-64 values which can be used as MAC Addresses, Bluetooth Device Addresses, Ethernet Addresses or object identifiers.
CID
A unique 24-bit identifier that cannot be used to generate EUI-48 or EUI-64 values. Therefore, the CID (Company ID) is especially applicable in applications where unique MAC addresses are not required.
