Which company owns MAC address prefix D0:BD:01?

MAC address prefix D0:BD:01 is registered to DS International in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:BD:01 has a network interface built by DS International.

What is the OUI D0:BD:01?

D0:BD:01 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DS International. It covers every address from D0:BD:01:00:00:00 to D0:BD:01:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-BD-01.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:BD:01:00:00:00 that is D0:BD:01 — 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 DS International located?

DS International is listed at 806ho, ACE HITECH21 B/D Busan Busan KR 612-020 in the IEEE OUI registry entry for D0:BD:01. This is the address the organization registered with the IEEE, which may differ from its current operating address.
