Which company owns MAC address prefix DC:2E:6A?

MAC address prefix DC:2E:6A is registered to HCT. Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:2E:6A has a network interface built by HCT. Co., Ltd..

What is the OUI DC:2E:6A?

DC:2E:6A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HCT. Co., Ltd.. It covers every address from DC:2E:6A:00:00:00 to DC:2E:6A:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-2E-6A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:2E:6A:00:00:00 that is DC:2E:6A — 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 HCT. Co., Ltd. located?

HCT. Co., Ltd. is listed at 105-1, Jangam-ri, Majang-myen Icheon-si Gyeonggi-do KR 467-811 in the IEEE OUI registry entry for DC:2E:6A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
