Which company owns MAC address prefix 2C:DD:0C?

MAC address prefix 2C:DD:0C is registered to Discovergy GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:DD:0C has a network interface built by Discovergy GmbH.

What is the OUI 2C:DD:0C?

2C:DD:0C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Discovergy GmbH. It covers every address from 2C:DD:0C:00:00:00 to 2C:DD:0C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 2C-DD-0C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:DD:0C:00:00:00 that is 2C:DD:0C — 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 Discovergy GmbH located?

Discovergy GmbH is listed at Pascalstraße 15 Aachen NRW DE 52076 in the IEEE OUI registry entry for 2C:DD:0C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
