Which company owns MAC address prefix BC:B6:FB?

MAC address prefix BC:B6:FB is registered to P4Q ELECTRONICS, S.L. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:B6:FB has a network interface built by P4Q ELECTRONICS, S.L..

What is the OUI BC:B6:FB?

BC:B6:FB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to P4Q ELECTRONICS, S.L.. It covers every address from BC:B6:FB:00:00:00 to BC:B6:FB:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-B6-FB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:B6:FB:00:00:00 that is BC:B6:FB — 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 P4Q ELECTRONICS, S.L. located?

P4Q ELECTRONICS, S.L. is listed at Calle Nuestra Señora de la Guía Número 19 Alonsotegi Bizkaia ES 48810 in the IEEE OUI registry entry for BC:B6:FB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
