Which company owns MAC address prefix 00:15:89?

MAC address prefix 00:15:89 is registered to D-MAX Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:15:89 has a network interface built by D-MAX Technology Co.,Ltd.

What is the OUI 00:15:89?

00:15:89 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to D-MAX Technology Co.,Ltd. It covers every address from 00:15:89:00:00:00 to 00:15:89:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-15-89.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:15:89:00:00:00 that is 00:15:89 — 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 D-MAX Technology Co.,Ltd located?

D-MAX Technology Co.,Ltd is listed at 7F-6,NO.26,Lian Cheng RD.,Chung-Ho City Taipei Hsien US 235 in the IEEE OUI registry entry for 00:15:89. This is the address the organization registered with the IEEE, which may differ from its current operating address.
