How can I know or detect the network information I use? . . Urgent. .

The first question (provided that you are adsl) is to double-click the broadband connection to the network connection status, switch to the details tab, find the ip address of the server inside, and check that address on the ip 138 website.

The second question is whether you usually dial through virtual dialing, adsl or lan.

The third problem is that the local area network is generally an intranet, so you belong to the intranet, but there is no doubt that you have the external address of adsl.

The fourth question is, put the mouse on the small computer in the lower right corner of the status bar and don't move. There will be a floating box inside. If there is no property in the lower right corner, right click to find local connection and broadband connection. Right-click on the property and let me know in the activity area (it depends on which network broadband you want to see. It doesn't make sense to be unfair, but the network card is useless.
