What is the OUI D4:F2:07?

D4:F2:07 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DIAODIAO(Beijing)Technology CO.,Ltd. It covers every address from D4:F2:07:00:00:00 to D4:F2:07:FF:FF:FF, or 16,777,216 addresses in total. It is also written D4-F2-07.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D4:F2:07:00:00:00 that is D4:F2:07 — 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 DIAODIAO(Beijing)Technology CO.,Ltd located?

DIAODIAO(Beijing)Technology CO.,Ltd is listed at 48D Image Base, No 3 Guangqu Road, Chaoyang District, Beijing, China Beijing CN 100124 in the IEEE OUI registry entry for D4:F2:07. This is the address the organization registered with the IEEE, which may differ from its current operating address.
