Which company owns MAC address prefix D0:31:10?

MAC address prefix D0:31:10 is registered to Ingenic Semiconductor Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:31:10 has a network interface built by Ingenic Semiconductor Co.,Ltd.

What is the OUI D0:31:10?

D0:31:10 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ingenic Semiconductor Co.,Ltd. It covers every address from D0:31:10:00:00:00 to D0:31:10:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-31-10.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:31:10:00:00:00 that is D0:31:10 — 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 Ingenic Semiconductor Co.,Ltd located?

Ingenic Semiconductor Co.,Ltd is listed at Room 108,Building A,Information Center Zhongguancun Software Park 8 Dongbeiwang West Road,Haidain District Beijing CN 100193 in the IEEE OUI registry entry for D0:31:10. This is the address the organization registered with the IEEE, which may differ from its current operating address.
