Which company owns MAC address prefix BC:15:A6?

MAC address prefix BC:15:A6 is registered to Taiwan Jantek Electronics,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:15:A6 has a network interface built by Taiwan Jantek Electronics,Ltd..

What is the OUI BC:15:A6?

BC:15:A6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Taiwan Jantek Electronics,Ltd.. It covers every address from BC:15:A6:00:00:00 to BC:15:A6:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-15-A6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:15:A6:00:00:00 that is BC:15:A6 — 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.
