Which company owns MAC address prefix 00:25:AB?

MAC address prefix 00:25:AB is registered to AIO LCD PC BU / TPV in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:25:AB has a network interface built by AIO LCD PC BU / TPV.

What is the OUI 00:25:AB?

00:25:AB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AIO LCD PC BU / TPV. It covers every address from 00:25:AB:00:00:00 to 00:25:AB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-25-AB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:25:AB:00:00:00 that is 00:25:AB — 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 AIO LCD PC BU / TPV located?

AIO LCD PC BU / TPV is listed at 10F., No., 230, Liancheng Rd. Zhonghe City Taipei Taiwan TW 23553 in the IEEE OUI registry entry for 00:25:AB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
