What is the OUI F0:8B:FE?

F0:8B:FE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to COSTEL.,CO.LTD. It covers every address from F0:8B:FE:00:00:00 to F0:8B:FE:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-8B-FE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:8B:FE:00:00:00 that is F0:8B:FE — 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 COSTEL.,CO.LTD located?

COSTEL.,CO.LTD is listed at 223-39, Sangdaewon-Dong, Jungwon-Gu Seongnam-si Kyunggi-Do KR 462-807 in the IEEE OUI registry entry for F0:8B:FE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
