Which company owns MAC address prefix 24:45:97?

MAC address prefix 24:45:97 is registered to GEMUE Gebr. Mueller Apparatebau in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:45:97 has a network interface built by GEMUE Gebr. Mueller Apparatebau.

What is the OUI 24:45:97?

24:45:97 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GEMUE Gebr. Mueller Apparatebau. It covers every address from 24:45:97:00:00:00 to 24:45:97:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-45-97.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:45:97:00:00:00 that is 24:45:97 — 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 GEMUE Gebr. Mueller Apparatebau located?

GEMUE Gebr. Mueller Apparatebau is listed at Fritz-Mueller-Strasse 6-8 Ingelfingen Criesbach DE 74653 in the IEEE OUI registry entry for 24:45:97. This is the address the organization registered with the IEEE, which may differ from its current operating address.
