Which company owns MAC address prefix AC:38:70?

MAC address prefix AC:38:70 is registered to Lenovo Mobile Communication Technology Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:38:70 has a network interface built by Lenovo Mobile Communication Technology Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:38:70:00:00:00 that is AC:38:70 — 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 Lenovo Mobile Communication Technology Ltd. located?
