Which company owns MAC address prefix B0:8B:9E?

MAC address prefix B0:8B:9E is registered to Telechips, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:8B:9E has a network interface built by Telechips, Inc..

What is the OUI B0:8B:9E?

B0:8B:9E 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 B0:8B:9E:00:00:00 to B0:8B:9E:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-8B-9E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:8B:9E:00:00:00 that is B0:8B:9E — 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 19F~23F,Luther Bldg.42, Olympic-ro 35da-gil, Songpa-gu, Seoul Seoul KR 05510 in the IEEE OUI registry entry for B0:8B:9E. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Telechips, Inc. own?

Telechips, Inc. holds 7 OUI prefixes in the IEEE registry, of which B0:8B:9E is one. A device made by Telechips, Inc. could carry a MAC address from any of them.
