Which company owns MAC address prefix A4:35:2D?

MAC address prefix A4:35:2D is registered to TRIZ Networks corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A4:35:2D has a network interface built by TRIZ Networks corp..

What is the OUI A4:35:2D?

A4:35:2D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TRIZ Networks corp.. It covers every address from A4:35:2D:00:00:00 to A4:35:2D:FF:FF:FF, or 16,777,216 addresses in total. It is also written A4-35-2D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A4:35:2D:00:00:00 that is A4:35:2D — 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 TRIZ Networks corp. located?

TRIZ Networks corp. is listed at 815 Daewangpangyo-ro Sujeong-gu, Seongnam-si Gyeonggi-do KR 13449 in the IEEE OUI registry entry for A4:35:2D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
