Which company owns MAC address prefix F8:4D:8B?

MAC address prefix F8:4D:8B is registered to ecamtek in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:4D:8B has a network interface built by ecamtek.

What is the OUI F8:4D:8B?

F8:4D:8B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ecamtek. It covers every address from F8:4D:8B:00:00:00 to F8:4D:8B:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-4D-8B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:4D:8B:00:00:00 that is F8:4D:8B — 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 ecamtek located?

ecamtek is listed at Sagimakgol-ro 62beon-gil, Jungwon-gu, Seongnam-si, Gyeonggi-do, KR 13211 in the IEEE OUI registry entry for F8:4D:8B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
