Which company owns MAC address prefix D0:D2:86?

MAC address prefix D0:D2:86 is registered to Beckman Coulter K.K. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:D2:86 has a network interface built by Beckman Coulter K.K..

What is the OUI D0:D2:86?

D0:D2:86 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Beckman Coulter K.K.. It covers every address from D0:D2:86:00:00:00 to D0:D2:86:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-D2-86.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:D2:86:00:00:00 that is D0:D2:86 — 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 Beckman Coulter K.K. located?

Beckman Coulter K.K. is listed at 454-32 Higashino, Nagaizumi-cho, Sunto-gun, Shizuoka-ken JP 411-0943 in the IEEE OUI registry entry for D0:D2:86. This is the address the organization registered with the IEEE, which may differ from its current operating address.
