Which company owns MAC address prefix C0:09:25?

MAC address prefix C0:09:25 is registered to FN-LINK TECHNOLOGY Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:09:25 has a network interface built by FN-LINK TECHNOLOGY Ltd..

What is the OUI C0:09:25?

C0:09:25 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to FN-LINK TECHNOLOGY Ltd.. It covers every address from C0:09:25:00:00:00 to C0:09:25:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-09-25.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:09:25:00:00:00 that is C0:09:25 — 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 FN-LINK TECHNOLOGY Ltd. located?

FN-LINK TECHNOLOGY Ltd. is listed at No.8, Litong Road, Liuyang Economic & Technical Development Zone, Changsha, Hunan,China Changsha Hunan CN 410329 in the IEEE OUI registry entry for C0:09:25. This is the address the organization registered with the IEEE, which may differ from its current operating address.
