Which company owns MAC address prefix A0:E6:17?

MAC address prefix A0:E6:17 is registered to MATIS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A0:E6:17 has a network interface built by MATIS.

What is the OUI A0:E6:17?

A0:E6:17 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MATIS. It covers every address from A0:E6:17:00:00:00 to A0:E6:17:FF:FF:FF, or 16,777,216 addresses in total. It is also written A0-E6-17.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A0:E6:17:00:00:00 that is A0:E6:17 — 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 MATIS located?

MATIS is listed at 2/F,Hatchobori MIYATA Bldg.,1-8-2, Shintomi,Chuo-Ku, Tokyo JP 104-0041 in the IEEE OUI registry entry for A0:E6:17. This is the address the organization registered with the IEEE, which may differ from its current operating address.
