Which company owns MAC address prefix BC:22:FB?

MAC address prefix BC:22:FB is registered to RF Industries in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:22:FB has a network interface built by RF Industries.

What is the OUI BC:22:FB?

BC:22:FB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to RF Industries. It covers every address from BC:22:FB:00:00:00 to BC:22:FB:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-22-FB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:22:FB:00:00:00 that is BC:22: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 RF Industries located?

RF Industries is listed at PO Box 5 Welland SA AU 5007 in the IEEE OUI registry entry for BC:22:FB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
