How to know the internet connection of your computer?

And are all these softwares licensed to communicate or not? There is a simple solution to this, and that is to use the netstat command in the Windows command line tool.
This command works on all three Windows 7, 8 and XP operating systems, but if you are still using Windows XP, Windows XP installed on your computer must have at least a Service Pack 2 add-on.
Using the net stat command, we can get a list of all the items that are connected to the Internet through our computer, and to use this command, we first need to run the Windows command line tool, or Command Prompt, with the administrative or admin access level. .
If you are using one of the versions of Windows 8, you can right-click on the Start button in the lower left corner of the screen and then select Command Prompt (admin) from the menu that appears.

Now, if the User Account Control feature is enabled on your Windows, a box similar to the one you see in the image may appear. You need to click yes on this card. If this feature is not enabled on you, the command line tool will run immediately. .
In the Windows Command Prompt tool window, type the following command and press Enter:
netstat -abf 5> activity.txt
In this command, option a- shows all the communications and listening ports, option -b also shows you what software has tried to connect to the Internet, and at the end of option -f the full name of each dns shows you that we can use it to know exactly where each connection is connected and from what direction. Option 5 in the command also checks the connections every 5 seconds and finally saves the final result in a file called activity.txt.
Wait for about 2 minutes after executing the command and then press and hold ctrl + c to stop checking and storing information about Internet connections.
By stopping the command you can go to the path where the activity.txt file is stored (this path is displayed in the command line window and in our example is the root of drive C) this file in the text editor Open it as a document and see the connections that were connected and disconnected by your command.
If you also enter the phrase activity.txt in the command line window and press the enter button, the file in question will open in the Windows Notepad software window.
