Which company owns MAC address prefix 0C:FC:83?

MAC address prefix 0C:FC:83 is registered to Airoha Technology Corp., in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:FC:83 has a network interface built by Airoha Technology Corp.,.

What is the OUI 0C:FC:83?

0C:FC:83 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Airoha Technology Corp.,. It covers every address from 0C:FC:83:00:00:00 to 0C:FC:83:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-FC-83.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:FC:83:00:00:00 that is 0C:FC:83 — 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 Airoha Technology Corp., located?

Airoha Technology Corp., is listed at 5F, No.6-5, Dushing Road , Hsinchu Science Park Hsinchu TW 300 in the IEEE OUI registry entry for 0C:FC:83. This is the address the organization registered with the IEEE, which may differ from its current operating address.
