Which company owns MAC address prefix 68:5E:6B?

MAC address prefix 68:5E:6B is registered to PowerRay Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:5E:6B has a network interface built by PowerRay Co., Ltd..

What is the OUI 68:5E:6B?

68:5E:6B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PowerRay Co., Ltd.. It covers every address from 68:5E:6B:00:00:00 to 68:5E:6B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-5E-6B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:5E:6B:00:00:00 that is 68:5E:6B — 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 PowerRay Co., Ltd. located?

PowerRay Co., Ltd. is listed at 7F-1, No 190, Sec 2, Chung Hsing Road, Sindian District New Taipei City TW 231 in the IEEE OUI registry entry for 68:5E:6B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
