Which company owns MAC address prefix 50:AD:92?

MAC address prefix 50:AD:92 is registered to NX Technologies in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:AD:92 has a network interface built by NX Technologies.

What is the OUI 50:AD:92?

50:AD:92 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NX Technologies. It covers every address from 50:AD:92:00:00:00 to 50:AD:92:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-AD-92.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:AD:92:00:00:00 that is 50:AD: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 NX Technologies located?

NX Technologies is listed at 5F(OS Building), 57, Daeril-2gil, Beomseo-eup Ulsan KR 44922 in the IEEE OUI registry entry for 50:AD:92. This is the address the organization registered with the IEEE, which may differ from its current operating address.
