Which company owns MAC address prefix 9C:C0:D2?

MAC address prefix 9C:C0:D2 is registered to Conductix-Wampfler GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:C0:D2 has a network interface built by Conductix-Wampfler GmbH.

What is the OUI 9C:C0:D2?

9C:C0:D2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Conductix-Wampfler GmbH. It covers every address from 9C:C0:D2:00:00:00 to 9C:C0:D2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-C0-D2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:C0:D2:00:00:00 that is 9C:C0:D2 — 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 Conductix-Wampfler GmbH located?

Conductix-Wampfler GmbH is listed at Rheinstrasse 27+33 Baden-Württemberg DE in the IEEE OUI registry entry for 9C:C0:D2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
