How to Get Port Number from IP Address in Windows 10: A Step-by-Step Guide

How to Get Port Number from IP Address in Windows 10

Finding the port number corresponding to an IP address in Windows 10 can be a bit tricky, but it’s not rocket science. Essentially, you need to use the Command Prompt and some basic networking commands. By following these steps, you can efficiently determine the port number associated with a particular IP address.

Step-by-Step Tutorial: How to Get Port Number from IP Address in Windows 10

The following steps will guide you through the process of finding the port number associated with a specific IP address using Windows 10.

Step 1: Open Command Prompt

First, open the Command Prompt by typing "cmd" in the Windows search bar and pressing Enter.

Opening the Command Prompt is like opening the gateway to your computer’s brain. It’s where you can input commands to get the info you need.

Step 2: Run the netstat Command

Type netstat -a and press Enter.

The netstat command will list all active connections and listening ports. Adding the -a option ensures that it shows both listening and non-listening ports.

Step 3: Find the IP Address

Look through the listed connections to find the one associated with the IP address you’re interested in.

This step may feel like finding a needle in a haystack if you have many connections, but you can use the scroll bar to make it easier.

Step 4: Note the Port Number

Once you locate the IP address, note the port number listed next to it.

The port number will usually follow the IP address, separated by a colon. For example, in 192.168.1.10:8080, 8080 is the port number.

Step 5: Verify the Port Number

For additional verification, you can use the netstat -an command, which will show numerical addresses and port numbers.

This step ensures that you’ve got the correct port number and haven’t missed it due to any formatting issues.

After completing these steps, you’ll know the specific port number associated with an IP address on Windows 10. This data can help diagnose network issues or ensure your firewall settings are correctly configured.

Tips for How to Get Port Number from IP Address in Windows 10

  1. Use Administrator Mode: Running Command Prompt as an administrator can sometimes provide more detailed information.
  2. Filter Results: Use the findstr command to filter results. For example, netstat -a | findstr "192.168.1.10" will only show connections related to that IP.
  3. Check Firewall Settings: Ensure your firewall isn’t blocking the port you are trying to find.
  4. Update Network Drivers: Sometimes, outdated network drivers can cause inaccuracies in the netstat output.
  5. Use Third-Party Tools: If Command Prompt feels too complex, tools like Wireshark can provide similar information with a graphical interface.
