Which company owns MAC address prefix D0:C3:1E?

MAC address prefix D0:C3:1E is registered to JUNGJIN Electronics Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:C3:1E has a network interface built by JUNGJIN Electronics Co.,Ltd.

What is the OUI D0:C3:1E?

D0:C3:1E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JUNGJIN Electronics Co.,Ltd. It covers every address from D0:C3:1E:00:00:00 to D0:C3:1E:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-C3-1E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:C3:1E:00:00:00 that is D0:C3:1E — 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 JUNGJIN Electronics Co.,Ltd located?

JUNGJIN Electronics Co.,Ltd is listed at 41-11, Yangjipyeon-ro Uiwang-si Gyeonggi-do KR 16007 in the IEEE OUI registry entry for D0:C3:1E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
