Which company owns MAC address prefix B0:67:2F?

MAC address prefix B0:67:2F is registered to Bowers & Wilkins in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:67:2F has a network interface built by Bowers & Wilkins.

What is the OUI B0:67:2F?

B0:67:2F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Bowers & Wilkins. It covers every address from B0:67:2F:00:00:00 to B0:67:2F:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-67-2F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:67:2F:00:00:00 that is B0:67:2F — 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 Bowers & Wilkins located?

Bowers & Wilkins is listed at 900 Middlefield Rd Floor 4 Redwood City CA US 94063 in the IEEE OUI registry entry for B0:67:2F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
