MAC Addresses

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 manufacturers 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.
