Which company owns MAC address prefix B0:8B:BE?

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

What is the OUI B0:8B:BE?

B0:8B:BE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ABL GmbH. It covers every address from B0:8B:BE:00:00:00 to B0:8B:BE:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-8B-BE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:8B:BE:00:00:00 that is B0:8B:BE — 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 ABL GmbH located?

ABL GmbH is listed at Albert-Buettner-Str. 11 Lauf DE 91207 in the IEEE OUI registry entry for B0:8B:BE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
