Which company owns MAC address prefix 18:32:A2?

MAC address prefix 18:32:A2 is registered to LAON TECHNOLOGY CO., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:32:A2 has a network interface built by LAON TECHNOLOGY CO., LTD..

What is the OUI 18:32:A2?

18:32:A2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LAON TECHNOLOGY CO., LTD.. It covers every address from 18:32:A2:00:00:00 to 18:32:A2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-32-A2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:32:A2:00:00:00 that is 18:32:A2 — 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 LAON TECHNOLOGY CO., LTD. located?

LAON TECHNOLOGY CO., LTD. is listed at #1212 HO, BIZ CENTER, SKn TECHNOPARK SEONGNAM KYOUNGGI DO KR 462-721 in the IEEE OUI registry entry for 18:32:A2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
