Which company owns MAC address prefix 28:F5:2B?

MAC address prefix 28:F5:2B is registered to FN-LINK TECHNOLOGY Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 28:F5:2B has a network interface built by FN-LINK TECHNOLOGY Ltd..

What is the OUI 28:F5:2B?

28:F5:2B 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 28:F5:2B:00:00:00 to 28:F5:2B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 28-F5-2B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 28:F5:2B:00:00:00 that is 28:F5:2B — 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 28:F5:2B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
