Which company owns MAC address prefix 04:2B:BB?

MAC address prefix 04:2B:BB is registered to PicoCELA, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:2B:BB has a network interface built by PicoCELA, Inc..

What is the OUI 04:2B:BB?

04:2B:BB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PicoCELA, Inc.. It covers every address from 04:2B:BB:00:00:00 to 04:2B:BB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-2B-BB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:2B:BB:00:00:00 that is 04:2B:BB — 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 PicoCELA, Inc. located?

PicoCELA, Inc. is listed at 3-8-33, Momochihama Fukuoka-city Fukuoka JP 814-0001 in the IEEE OUI registry entry for 04:2B:BB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
