Which company owns MAC address prefix 7C:2F:80?

MAC address prefix 7C:2F:80 is registered to Gigaset Communications GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 7C:2F:80 has a network interface built by Gigaset Communications GmbH.

What is the OUI 7C:2F:80?

7C:2F:80 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Gigaset Communications GmbH. It covers every address from 7C:2F:80:00:00:00 to 7C:2F:80:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-2F-80.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:2F:80:00:00:00 that is 7C:2F:80 — 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 Gigaset Communications GmbH located?

Gigaset Communications GmbH is listed at SCM PE 2 Bocholt DE 46395 in the IEEE OUI registry entry for 7C:2F:80. This is the address the organization registered with the IEEE, which may differ from its current operating address.
