Which company owns MAC address prefix A8:01:6D?

MAC address prefix A8:01:6D is registered to Aiwa Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:01:6D has a network interface built by Aiwa Corporation.

What is the OUI A8:01:6D?

A8:01:6D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Aiwa Corporation. It covers every address from A8:01:6D:00:00:00 to A8:01:6D:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-01-6D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:01:6D:00:00:00 that is A8:01:6D — 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 Aiwa Corporation located?

Aiwa Corporation is listed at 965 W Chicago Ave Chicago IL US 60642 in the IEEE OUI registry entry for A8:01:6D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
