Which company owns MAC address prefix 08:0F:FA?

MAC address prefix 08:0F:FA is registered to KSP INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:0F:FA has a network interface built by KSP INC..

What is the OUI 08:0F:FA?

08:0F:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KSP INC.. It covers every address from 08:0F:FA:00:00:00 to 08:0F:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-0F-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:0F:FA:00:00:00 that is 08:0F: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 KSP INC. located?

KSP INC. is listed at RM 501, 138 Kwangdeokdae-ro Danwon-gu, Ansan-si Gyeonggi-do KR 425906 in the IEEE OUI registry entry for 08:0F:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
