Which company owns MAC address prefix D0:6A:1F?

MAC address prefix D0:6A:1F is registered to BSE CO.,LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:6A:1F has a network interface built by BSE CO.,LTD..

What is the OUI D0:6A:1F?

D0:6A:1F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BSE CO.,LTD.. It covers every address from D0:6A:1F:00:00:00 to D0:6A:1F:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-6A-1F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:6A:1F:00:00:00 that is D0:6A:1F — 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 BSE CO.,LTD. located?

BSE CO.,LTD. is listed at 626-3, Gozan-dong, Namdong-ku Incheon, 405-817 KR in the IEEE OUI registry entry for D0:6A:1F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
