Which company owns MAC address prefix 5C:7B:6C?

MAC address prefix 5C:7B:6C is registered to Tradit Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:7B:6C has a network interface built by Tradit Co., Ltd.

What is the OUI 5C:7B:6C?

5C:7B:6C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tradit Co., Ltd. It covers every address from 5C:7B:6C:00:00:00 to 5C:7B:6C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-7B-6C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:7B:6C:00:00:00 that is 5C:7B:6C — 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 Tradit Co., Ltd located?

Tradit Co., Ltd is listed at #617, 416 Hwagok-ro, Gangseo-gu Seoul KR 07548 in the IEEE OUI registry entry for 5C:7B:6C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
