Which company owns MAC address prefix 5C:8D:FD?

MAC address prefix 5C:8D:FD is registered to Clariphotonics CO., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:8D:FD has a network interface built by Clariphotonics CO., Ltd.

What is the OUI 5C:8D:FD?

5C:8D:FD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Clariphotonics CO., Ltd. It covers every address from 5C:8D:FD:00:00:00 to 5C:8D:FD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-8D-FD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:8D:FD:00:00:00 that is 5C:8D:FD — 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 Clariphotonics CO., Ltd located?

Clariphotonics CO., Ltd is listed at 7F-2, No. 20, Fuxing 1st Rd., Zhubei Zhubei TW 30256 in the IEEE OUI registry entry for 5C:8D:FD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
