Which company owns MAC address prefix 00:80:17?

MAC address prefix 00:80:17 is registered to PFU LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:80:17 has a network interface built by PFU LIMITED.

What is the OUI 00:80:17?

00:80:17 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PFU LIMITED. It covers every address from 00:80:17:00:00:00 to 00:80:17:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-80-17.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:80:17:00:00:00 that is 00:80:17 — 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 PFU LIMITED located?

PFU LIMITED is listed at Nu 98-2 Unoke Kahoku-shi, Ishikawa JP 929-1192 in the IEEE OUI registry entry for 00:80:17. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does PFU LIMITED own?

PFU LIMITED holds 2 OUI prefixes in the IEEE registry, of which 00:80:17 is one. A device made by PFU LIMITED could carry a MAC address from any of them.
