Which company owns MAC address prefix B8:DF:6B?

MAC address prefix B8:DF:6B is registered to SpotCam Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:DF:6B has a network interface built by SpotCam Co., Ltd..

What is the OUI B8:DF:6B?

B8:DF:6B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SpotCam Co., Ltd.. It covers every address from B8:DF:6B:00:00:00 to B8:DF:6B:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-DF-6B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:DF:6B:00:00:00 that is B8:DF:6B — 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 SpotCam Co., Ltd. located?

SpotCam Co., Ltd. is listed at 12F.-1, No.125, Jianguo Rd. New Taipei City TW 239 in the IEEE OUI registry entry for B8:DF:6B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
