The code is found online, but has been modified.

The reason is that if you have more than one network card in your notebook, it will appear to get the information that you are not connected to the Internet or the network card is disabled.

ObjObject DNSServerSearchOrder! = null

Add this constraint, you can get the network client network card IP address.

One problem is that you can only limit Internet explorer, and Activex must be fully enabled.
