What is the OUI FC:F7:63?

FC:F7:63 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KunGao Micro (JiangSu) Co., LTd. It covers every address from FC:F7:63:00:00:00 to FC:F7:63:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-F7-63.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:F7:63:00:00:00 that is FC:F7:63 — 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 KunGao Micro (JiangSu) Co., LTd located?
