Which company owns MAC address prefix 58:08:FA?

MAC address prefix 58:08:FA is registered to Fiber Optic & telecommunication INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:08:FA has a network interface built by Fiber Optic & telecommunication INC..

What is the OUI 58:08:FA?

58:08:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Fiber Optic & telecommunication INC.. It covers every address from 58:08:FA:00:00:00 to 58:08:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-08-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:08:FA:00:00:00 that is 58:08: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 Fiber Optic & telecommunication INC. located?

Fiber Optic & telecommunication INC. is listed at 161-4 Kumjeong-Dong, Kunpo-city Gyeonggi-Do KR 435-824 in the IEEE OUI registry entry for 58:08:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
