What is the OUI C4:C0:AE?

C4:C0:AE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MIDORI ELECTRONIC CO., LTD.. It covers every address from C4:C0:AE:00:00:00 to C4:C0:AE:FF:FF:FF, or 16,777,216 addresses in total. It is also written C4-C0-AE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:C0:AE:00:00:00 that is C4:C0: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 MIDORI ELECTRONIC CO., LTD. located?

MIDORI ELECTRONIC CO., LTD. is listed at 397 Chikuma Nagano JP 389-0804 in the IEEE OUI registry entry for C4:C0:AE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
