Which company owns MAC address prefix 1C:1E:E3?

MAC address prefix 1C:1E:E3 is registered to Hui Zhou Gaoshengda Technology Co.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:1E:E3 has a network interface built by Hui Zhou Gaoshengda Technology Co.,LTD.

What is the OUI 1C:1E:E3?

1C:1E:E3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hui Zhou Gaoshengda Technology Co.,LTD. It covers every address from 1C:1E:E3:00:00:00 to 1C:1E:E3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-1E-E3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 1C:1E:E3:00:00:00 that is 1C:1E:E3 — 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.
