What is the OUI C8:F3:86?

C8:F3:86 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Xiaoniao Technology Co.,Ltd. It covers every address from C8:F3:86:00:00:00 to C8:F3:86:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-F3-86.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:F3:86:00:00:00 that is C8:F3:86 — 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 Shenzhen Xiaoniao Technology Co.,Ltd located?

Shenzhen Xiaoniao Technology Co.,Ltd is listed at Floor 13 C-D Yunsong Buliding Futian District, Shenzhen Guangdong CN 518040 in the IEEE OUI registry entry for C8:F3:86. This is the address the organization registered with the IEEE, which may differ from its current operating address.
