Which company owns MAC address prefix 1C:9E:CB?

MAC address prefix 1C:9E:CB is registered to Beijing Nari Smartchip Microelectronics Company Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:9E:CB has a network interface built by Beijing Nari Smartchip Microelectronics Company Limited.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 1C:9E:CB:00:00:00 that is 1C:9E:CB — 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.
