Which company owns MAC address prefix 80:2A:FA?

MAC address prefix 80:2A:FA is registered to Germaneers GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:2A:FA has a network interface built by Germaneers GmbH.

What is the OUI 80:2A:FA?

80:2A:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Germaneers GmbH. It covers every address from 80:2A:FA:00:00:00 to 80:2A:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-2A-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:2A:FA:00:00:00 that is 80:2A:FA — 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 Germaneers GmbH located?

Germaneers GmbH is listed at Dr.-Kurt-Schumacher-Ring 3 Wettstetten Bayern DE 85139 in the IEEE OUI registry entry for 80:2A:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
