Which company owns MAC address prefix 44:EE:02?

MAC address prefix 44:EE:02 is registered to MTI Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:EE:02 has a network interface built by MTI Ltd..

What is the OUI 44:EE:02?

44:EE:02 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MTI Ltd.. It covers every address from 44:EE:02:00:00:00 to 44:EE:02:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-EE-02.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:EE:02:00:00:00 that is 44:EE:02 — 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 MTI Ltd. located?

MTI Ltd. is listed at Nishi-shinjuku Tokyo Opera City Tower 3-20-2 35F Shinjuku-ku Tokyo JP 163-1435 in the IEEE OUI registry entry for 44:EE:02. This is the address the organization registered with the IEEE, which may differ from its current operating address.
