To use the port number and the IP address under which it is located on the network, it is necessary to determine which port which IP address currently corresponds to. Each of them will have special flags that tell the user about the assigned Windows process ID numbers.

Step 1
The algorithm for determining the IP address of a port varies depending on what devices and resources are currently in use. For a user computer located on the Internet with access to certain resources, the algorithm will be as follows: -Open a command prompt. To do this, go to the "Start" menu, click on the "Run" item, and using the keyboard enter the cmd command. This action will bring up a black window, a command line window. -Enter the command ping_server_site in the command window using the keyboard, server_site - the address of a resource on the Network. Click Enter to execute the command. A table with IP addresses and corresponding resources will open in the command prompt window.
Step 2
If the port is used by a certain device, then you will need to perform a number of simple steps to determine the IP address of this device: -Activate the device, the IP address of the port of which is supposed to be determined. Open the command line with the steps described above - go to the "Start" menu, click on "Run", and use the keyboard keys to enter cmd. Press Enter to execute the command. - Type netstate in the Command Prompt window using your keyboard and press Enter to execute it. The Command Prompt window will display each device-enabled connection and the port IDs opposite them.
Step 3
Alternatively, you can use the NETSTAT-AON | MORE command instead of the last command. This command will display on the right side of the command line window a list of PIDs, process identifiers. In the illustration, you can see that the PID of a device with an IP address of 0.0.0.0:80, that is, assigned to the eightieth port, will be 4708.
Step 4
Now the user can simply download the task manager - it is likely that they will need to use the "Show processes for each user" option, and the PID will be found in the list of applications - it can be used to determine which application is controlling the device with a given IP.
Step 5
Using information about the IP addresses of devices can help maintain anonymity on the network and help protect your operating system. You cannot refuse to use it, since IP is necessary for routing information. At the same time, you can configure the connection of devices and applications through a proxy server, which will receive and send data as if on its own behalf. However, the overwhelming majority of them indicate the address of end users in the x-forwarded-for service field.
