Which company owns MAC address prefix 50:0A:52?

MAC address prefix 50:0A:52 is registered to Huiwan Technologies Co. Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:0A:52 has a network interface built by Huiwan Technologies Co. Ltd.

What is the OUI 50:0A:52?

50:0A:52 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Huiwan Technologies Co. Ltd. It covers every address from 50:0A:52:00:00:00 to 50:0A:52:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-0A-52.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:0A:52:00:00:00 that is 50:0A:52 — 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 Huiwan Technologies Co. Ltd located?
