Which company owns MAC address prefix 54:F2:9F?

MAC address prefix 54:F2:9F is registered to HUNAN FN-LINK TECHNOLOGY LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:F2:9F has a network interface built by HUNAN FN-LINK TECHNOLOGY LIMITED.

What is the OUI 54:F2:9F?

54:F2:9F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HUNAN FN-LINK TECHNOLOGY LIMITED. It covers every address from 54:F2:9F:00:00:00 to 54:F2:9F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-F2-9F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:F2:9F:00:00:00 that is 54:F2:9F — 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 HUNAN FN-LINK TECHNOLOGY LIMITED located?

HUNAN FN-LINK TECHNOLOGY LIMITED is listed at No.8, Litong Road, Liuyan Economic & Tec Changsha HUNAN CN 410329 in the IEEE OUI registry entry for 54:F2:9F. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does HUNAN FN-LINK TECHNOLOGY LIMITED own?

HUNAN FN-LINK TECHNOLOGY LIMITED holds 13 OUI prefixes in the IEEE registry, of which 54:F2:9F is one. A device made by HUNAN FN-LINK TECHNOLOGY LIMITED could carry a MAC address from any of them.
