Which company owns MAC address prefix 6C:A7:FA?

MAC address prefix 6C:A7:FA is registered to YOUNGBO ENGINEERING INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 6C:A7:FA has a network interface built by YOUNGBO ENGINEERING INC..

What is the OUI 6C:A7:FA?

6C:A7:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to YOUNGBO ENGINEERING INC.. It covers every address from 6C:A7:FA:00:00:00 to 6C:A7:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-A7-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:A7:FA:00:00:00 that is 6C:A7:FA — 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 YOUNGBO ENGINEERING INC. located?

YOUNGBO ENGINEERING INC. is listed at 132, Haewian-gil, Dunpo-myeon Asan-si Chungcheongnam-do KR 336-873 in the IEEE OUI registry entry for 6C:A7:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
