Which company owns MAC address prefix CC:2A:AC?

MAC address prefix CC:2A:AC is registered to Yunjing lntelligent Technology(Dongguan).,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:2A:AC has a network interface built by Yunjing lntelligent Technology(Dongguan).,Ltd.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:2A:AC:00:00:00 that is CC:2A:AC — 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 Yunjing lntelligent Technology(Dongguan).,Ltd located?
