Which company owns MAC address prefix BC:14:EF?

MAC address prefix BC:14:EF is registered to ITON Technology Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:14:EF has a network interface built by ITON Technology Limited.

What is the OUI BC:14:EF?

BC:14:EF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ITON Technology Limited. It covers every address from BC:14:EF:00:00:00 to BC:14:EF:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-14-EF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:14:EF:00:00:00 that is BC:14:EF — 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 ITON Technology Limited located?

ITON Technology Limited is listed at Room 1302,A ablock, Building 4 ShenZhen GuangDong Pronvice CN 518000 in the IEEE OUI registry entry for BC:14:EF. This is the address the organization registered with the IEEE, which may differ from its current operating address.
