Which company owns MAC address prefix B0:B3:2B?

MAC address prefix B0:B3:2B is registered to Slican Sp. z o.o. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:B3:2B has a network interface built by Slican Sp. z o.o..

What is the OUI B0:B3:2B?

B0:B3:2B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Slican Sp. z o.o.. It covers every address from B0:B3:2B:00:00:00 to B0:B3:2B:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-B3-2B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:B3:2B:00:00:00 that is B0:B3:2B — 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 Slican Sp. z o.o. located?

Slican Sp. z o.o. is listed at M. Konopnickiej 18 Bydgoszcz Kujawsko-Pomorskie PL 85-124 in the IEEE OUI registry entry for B0:B3:2B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
