Which company owns MAC address prefix 00:24:FA?

MAC address prefix 00:24:FA is registered to Hilger u. Kern GMBH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:24:FA has a network interface built by Hilger u. Kern GMBH.

What is the OUI 00:24:FA?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:24:FA:00:00:00 that is 00:24: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 Hilger u. Kern GMBH located?

Hilger u. Kern GMBH is listed at Kaefertaler Strasse 253-255 Mannheim Baden-Württemberg DE 68167 in the IEEE OUI registry entry for 00:24:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
