Which company owns MAC address prefix 50:8A:06?

MAC address prefix 50:8A:06 is registered to Tuya Smart Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:8A:06 has a network interface built by Tuya Smart Inc..

What is the OUI 50:8A:06?

50:8A:06 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tuya Smart Inc.. It covers every address from 50:8A:06:00:00:00 to 50:8A:06:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-8A-06.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:8A:06:00:00:00 that is 50:8A:06 — 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 Tuya Smart Inc. located?

Tuya Smart Inc. is listed at 160 Greentree Drive, Suite 101 Dover DE US 19904 in the IEEE OUI registry entry for 50:8A:06. This is the address the organization registered with the IEEE, which may differ from its current operating address.
