Which company owns MAC address prefix 10:38:1F?

MAC address prefix 10:38:1F is registered to Sichuan AI-Link Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:38:1F has a network interface built by Sichuan AI-Link Technology Co., Ltd..

What is the OUI 10:38:1F?

10:38:1F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sichuan AI-Link Technology Co., Ltd.. It covers every address from 10:38:1F:00:00:00 to 10:38:1F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-38-1F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:38:1F:00:00:00 that is 10:38:1F — 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 Sichuan AI-Link Technology Co., Ltd. located?

Sichuan AI-Link Technology Co., Ltd. is listed at Anzhou, Industrial Park Mianyang Sichuan CN 622650 in the IEEE OUI registry entry for 10:38:1F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
