Which company owns MAC address prefix 00:60:21?

MAC address prefix 00:60:21 is registered to DSC CORPORATION in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:60:21 has a network interface built by DSC CORPORATION.

What is the OUI 00:60:21?

00:60:21 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DSC CORPORATION. It covers every address from 00:60:21:00:00:00 to 00:60:21:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-60-21.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:60:21:00:00:00 that is 00:60:21 — 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 DSC CORPORATION located?

DSC CORPORATION is listed at RECRUIT-SHINOHTSUKA BLDG., TOKYO 170 JP in the IEEE OUI registry entry for 00:60:21. This is the address the organization registered with the IEEE, which may differ from its current operating address.
