Which company owns MAC address prefix D0:F5:20?

MAC address prefix D0:F5:20 is registered to KYOCERA Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:F5:20 has a network interface built by KYOCERA Corporation.

What is the OUI D0:F5:20?

D0:F5:20 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KYOCERA Corporation. It covers every address from D0:F5:20:00:00:00 to D0:F5:20:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-F5-20.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:F5:20:00:00:00 that is D0:F5:20 — 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 KYOCERA Corporation located?

KYOCERA Corporation is listed at 30 Hoji Kitami, Hokkaido JP 099-1595 in the IEEE OUI registry entry for D0:F5:20. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does KYOCERA Corporation own?

KYOCERA Corporation holds 4 OUI prefixes in the IEEE registry, of which D0:F5:20 is one. A device made by KYOCERA Corporation could carry a MAC address from any of them.
