In the burgeoning Internet of Things (IoT) age, billions of devices will need to communicate with one another. To do this, Media Access Control (MAC) addresses are often needed by technology manufactures implementing IEEE 802® networking standards, most notably IEEE 802.3® (Ethernet) and IEEE 802.11™ (Wi-Fi®).

The IEEE Registration Authority makes MAC addresses available in Small, Medium, and Large blocks.

But how do I know what size MAC address block is right for my company?

Check out the infographic to determine the right size MAC address for your business.

An MA-L 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.
MAC Address Block Large (MA-L)

An MA-M 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.
MAC Address Block Medium (MA-M)

An MA-S 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.
MAC Address Block Small (MA-S)
