Which company owns MAC address prefix 14:C1:FF?

MAC address prefix 14:C1:FF is registered to ShenZhen QianHai Comlan communication Co.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:C1:FF has a network interface built by ShenZhen QianHai Comlan communication Co.,LTD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:C1:FF:00:00:00 that is 14:C1:FF — 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.
