Which company owns MAC address prefix 60:D5:1B?

MAC address prefix 60:D5:1B is registered to Fujitsu Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:D5:1B has a network interface built by Fujitsu Limited.

What is the OUI 60:D5:1B?

60:D5:1B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Fujitsu Limited. It covers every address from 60:D5:1B:00:00:00 to 60:D5:1B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-D5-1B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:D5:1B:00:00:00 that is 60:D5:1B — 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 Fujitsu Limited located?

Fujitsu Limited is listed at 4-1-1 Kamikodanaka, Nakahara-ku Kawasaki-shi Kanagawa JP 211-8588 in the IEEE OUI registry entry for 60:D5:1B. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Fujitsu Limited own?

Fujitsu Limited holds 3 OUI prefixes in the IEEE registry, of which 60:D5:1B is one. A device made by Fujitsu Limited could carry a MAC address from any of them.
