Which company owns MAC address prefix 9C:A6:9D?

MAC address prefix 9C:A6:9D is registered to Whaley Technology Co.Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:A6:9D has a network interface built by Whaley Technology Co.Ltd.

What is the OUI 9C:A6:9D?

9C:A6:9D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Whaley Technology Co.Ltd. It covers every address from 9C:A6:9D:00:00:00 to 9C:A6:9D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-A6-9D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:A6:9D:00:00:00 that is 9C:A6:9D — 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 Whaley Technology Co.Ltd located?

Whaley Technology Co.Ltd is listed at Floor 3, Building E, No666 Shengxia Road Shanghai CN 201203 in the IEEE OUI registry entry for 9C:A6:9D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
