Which company owns MAC address prefix DC:16:A2?

MAC address prefix DC:16:A2 is registered to Medtronic Diabetes in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:16:A2 has a network interface built by Medtronic Diabetes.

What is the OUI DC:16:A2?

DC:16:A2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Medtronic Diabetes. It covers every address from DC:16:A2:00:00:00 to DC:16:A2:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-16-A2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:16:A2:00:00:00 that is DC:16:A2 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Medtronic Diabetes located?

Medtronic Diabetes is listed at 18000 Devonshire St Northridge CA US 91325 in the IEEE OUI registry entry for DC:16:A2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
