Which company owns MAC address prefix F4:50:EB?

MAC address prefix F4:50:EB is registered to Telechips Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F4:50:EB has a network interface built by Telechips Inc.

What is the OUI F4:50:EB?

F4:50:EB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Telechips Inc. It covers every address from F4:50:EB:00:00:00 to F4:50:EB:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-50-EB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:50:EB:00:00:00 that is F4:50:EB — 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 Telechips Inc located?

Telechips Inc is listed at KORAD Bldg,1000-12, Daechi-Dong, Gangnam-Gu, Seoul KR 135-280 in the IEEE OUI registry entry for F4:50:EB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
