Which company owns MAC address prefix 80:0A:06?

MAC address prefix 80:0A:06 is registered to COMTEC co.,ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:0A:06 has a network interface built by COMTEC co.,ltd.

What is the OUI 80:0A:06?

80:0A:06 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to COMTEC co.,ltd. It covers every address from 80:0A:06:00:00:00 to 80:0A:06:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-0A-06.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:0A:06:00:00:00 that is 80:0A:06 — 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 COMTEC co.,ltd located?

COMTEC co.,ltd is listed at 60 shimoishida,azabu-cho, Miyoshi-shi Aichi-ken JP 470-0206 in the IEEE OUI registry entry for 80:0A:06. This is the address the organization registered with the IEEE, which may differ from its current operating address.
