Which company owns MAC address prefix BC:12:2F?

MAC address prefix BC:12:2F is registered to LCFC(Hefei) Electronics Technology co., ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:12:2F has a network interface built by LCFC(Hefei) Electronics Technology co., ltd.

What is the OUI BC:12:2F?

BC:12:2F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LCFC(Hefei) Electronics Technology co., ltd. It covers every address from BC:12:2F:00:00:00 to BC:12:2F:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-12-2F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:12:2F:00:00:00 that is BC:12:2F — 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 LCFC(Hefei) Electronics Technology co., ltd located?

LCFC(Hefei) Electronics Technology co., ltd is listed at No. 3188-1 Yungu Road (Comprehensive Bonded Zone), Hefei Economic & Technological Development Area，Anhui HEFEI ANHUI CN 230601 in the IEEE OUI registry entry for BC:12:2F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
