Which company owns MAC address prefix 3C:0D:2C?

What is the OUI 3C:0D:2C?

3C:0D:2C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Liquid-Markets GmbH. It covers every address from 3C:0D:2C:00:00:00 to 3C:0D:2C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 3C-0D-2C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 3C:0D:2C:00:00:00 that is 3C:0D:2C — 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 Liquid-Markets GmbH located?

Liquid-Markets GmbH is listed at Obermühle 8 Baar Zug CH 6340 in the IEEE OUI registry entry for 3C:0D:2C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
