Which company owns MAC address prefix 00:06:AB?

MAC address prefix 00:06:AB is registered to W-Link Systems, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:06:AB has a network interface built by W-Link Systems, Inc..

What is the OUI 00:06:AB?

00:06:AB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to W-Link Systems, Inc.. It covers every address from 00:06:AB:00:00:00 to 00:06:AB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-06-AB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:06:AB:00:00:00 that is 00:06: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 W-Link Systems, Inc. located?

W-Link Systems, Inc. is listed at No. 20, Park Ave. II, Hsinchu TW 300 in the IEEE OUI registry entry for 00:06:AB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
