Which company owns MAC address prefix 9C:54:1C?

MAC address prefix 9C:54:1C is registered to Shenzhen My-power Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:54:1C has a network interface built by Shenzhen My-power Technology Co.,Ltd.

What is the OUI 9C:54:1C?

9C:54:1C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen My-power Technology Co.,Ltd. It covers every address from 9C:54:1C:00:00:00 to 9C:54:1C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-54-1C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:54:1C:00:00:00 that is 9C:54:1C — 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 My-power Technology Co.,Ltd located?

Shenzhen My-power Technology Co.,Ltd is listed at 202¬Building 3¬Shenzhen Software Park Shenzhen Nanshan CN 518000 in the IEEE OUI registry entry for 9C:54:1C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
