Which company owns MAC address prefix DC:4E:DE?

MAC address prefix DC:4E:DE is registered to SHINYEI TECHNOLOGY CO., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:4E:DE has a network interface built by SHINYEI TECHNOLOGY CO., LTD..

What is the OUI DC:4E:DE?

DC:4E:DE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SHINYEI TECHNOLOGY CO., LTD.. It covers every address from DC:4E:DE:00:00:00 to DC:4E:DE:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-4E-DE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:4E:DE:00:00:00 that is DC:4E:DE — 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 SHINYEI TECHNOLOGY CO., LTD. located?

SHINYEI TECHNOLOGY CO., LTD. is listed at 6-5-2, MINATOJIMA-MINAMIMACHI, CHUO-KU KOBE HYOGO JP 650-0047 in the IEEE OUI registry entry for DC:4E:DE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
