Which company owns MAC address prefix 84:6A:ED?

MAC address prefix 84:6A:ED is registered to Wireless Tsukamoto.,co.LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:6A:ED has a network interface built by Wireless Tsukamoto.,co.LTD.

What is the OUI 84:6A:ED?

84:6A:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wireless Tsukamoto.,co.LTD. It covers every address from 84:6A:ED:00:00:00 to 84:6A:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-6A-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:6A:ED:00:00:00 that is 84:6A:ED — 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 Wireless Tsukamoto.,co.LTD located?

Wireless Tsukamoto.,co.LTD is listed at 16-21 1chome,Isoyama Suzuka Mie-pref JP 5100256 in the IEEE OUI registry entry for 84:6A:ED. This is the address the organization registered with the IEEE, which may differ from its current operating address.
