Which company owns MAC address prefix 00:0C:6B?

MAC address prefix 00:0C:6B is registered to Kurz Industrie-Elektronik GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0C:6B has a network interface built by Kurz Industrie-Elektronik GmbH.

What is the OUI 00:0C:6B?

00:0C:6B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Kurz Industrie-Elektronik GmbH. It covers every address from 00:0C:6B:00:00:00 to 00:0C:6B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0C-6B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0C:6B:00:00:00 that is 00:0C:6B — 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 Kurz Industrie-Elektronik GmbH located?

Kurz Industrie-Elektronik GmbH is listed at Foehrenbachstraße 3 Remshalden Baden-Württemberg DE 73630 in the IEEE OUI registry entry for 00:0C:6B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
