Which company owns MAC address prefix DC:C1:01?

MAC address prefix DC:C1:01 is registered to SOLiD Technologies, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:C1:01 has a network interface built by SOLiD Technologies, Inc..

What is the OUI DC:C1:01?

DC:C1:01 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SOLiD Technologies, Inc.. It covers every address from DC:C1:01:00:00:00 to DC:C1:01:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-C1-01.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:C1:01:00:00:00 that is DC:C1:01 — 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 SOLiD Technologies, Inc. located?

SOLiD Technologies, Inc. is listed at 9th Floor, SOLiD Space, Pangyoyeok-ro 220 Seongnam-si Gyeonggi-do KR 463-400 in the IEEE OUI registry entry for DC:C1:01. This is the address the organization registered with the IEEE, which may differ from its current operating address.
