Which company owns MAC address prefix 0C:FD:37?

MAC address prefix 0C:FD:37 is registered to SUSE Linux GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:FD:37 has a network interface built by SUSE Linux GmbH.

What is the OUI 0C:FD:37?

0C:FD:37 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SUSE Linux GmbH. It covers every address from 0C:FD:37:00:00:00 to 0C:FD:37:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-FD-37.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:FD:37:00:00:00 that is 0C:FD:37 — 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 SUSE Linux GmbH located?

SUSE Linux GmbH is listed at Maxfeldstraße 5 Nürnberg Bavaria DE 90409 in the IEEE OUI registry entry for 0C:FD:37. This is the address the organization registered with the IEEE, which may differ from its current operating address.
