Which company owns MAC address prefix 54:3D:92?

MAC address prefix 54:3D:92 is registered to WIRELESS-TEK TECHNOLOGY LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:3D:92 has a network interface built by WIRELESS-TEK TECHNOLOGY LIMITED.

What is the OUI 54:3D:92?

54:3D:92 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WIRELESS-TEK TECHNOLOGY LIMITED. It covers every address from 54:3D:92:00:00:00 to 54:3D:92:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-3D-92.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:3D:92:00:00:00 that is 54:3D:92 — 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 WIRELESS-TEK TECHNOLOGY LIMITED located?

WIRELESS-TEK TECHNOLOGY LIMITED is listed at Room 402 4F, BiaoFan Technology Building, Bao'An Avenue, FuYong Town, Bao'An district, ShenZhen,China SHENZHEN CN 518000 in the IEEE OUI registry entry for 54:3D:92. This is the address the organization registered with the IEEE, which may differ from its current operating address.
