Which company owns MAC address prefix 08:B0:A7?

MAC address prefix 08:B0:A7 is registered to Truebeyond Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:B0:A7 has a network interface built by Truebeyond Co., Ltd.

What is the OUI 08:B0:A7?

08:B0:A7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Truebeyond Co., Ltd. It covers every address from 08:B0:A7:00:00:00 to 08:B0:A7:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-B0-A7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:B0:A7:00:00:00 that is 08:B0:A7 — 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 Truebeyond Co., Ltd located?

Truebeyond Co., Ltd is listed at D-906, 60, Haan-ro Gwangmyeong Gyeonggi KR 14322 in the IEEE OUI registry entry for 08:B0:A7. This is the address the organization registered with the IEEE, which may differ from its current operating address.
