Which company owns MAC address prefix 18:38:AE?

MAC address prefix 18:38:AE is registered to CONSPIN SOLUTION in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:38:AE has a network interface built by CONSPIN SOLUTION.

What is the OUI 18:38:AE?

18:38:AE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CONSPIN SOLUTION. It covers every address from 18:38:AE:00:00:00 to 18:38:AE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-38-AE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:38:AE:00:00:00 that is 18:38:AE — 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 CONSPIN SOLUTION located?

CONSPIN SOLUTION is listed at 2F, Geonwoong Bldg. 109, Gwanak-ro, Gwanak-gu Seoul KR 08833 in the IEEE OUI registry entry for 18:38:AE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
