If you’re like me, you constantly need your IP in Windows. When working with network interfaces and multiple servers, I find myself checking my IP a lot.

I built a little utility for myself that only shows the IP addresses on the host, rather than typing ipconfig and getting a long list, I can simply type “ip” and it will only show IP addresses.

C++ Version of the Tool

The following compiles with GCC for Windows, and probably a lot of other compilers as well. This utility is standalone and only needs to be copied into a folder within your path.

Create a file called ip.cpp and add the following:

#include <iostream>
#include <stdio.h>
#include <typeinfo>
using namespace std;

int main()
    FILE *dir;
    char direntry[80];

    dir = popen("ipconfig", "r");

    while (!feof(dir)) {

        fgets(direntry, sizeof(direntry), dir);

        string output = direntry;

        if ((output.find("IP") != string::npos)) {
            cout << direntry << "\n";

    return 0;

This simple executable will cut down your time by only showing the information you need at the time. I hope this helps someone.

C# Version of the Tool

I have also created a C# version of this tool, but it requires the .NET framework to be installed. Create a file called IP.cs with the following code:

using System;

namespace iptools
    class ip

        static void Main(string[] args)

            //Create process
            System.Diagnostics.Process pProcess = new System.Diagnostics.Process();

            //the command we want to run
            pProcess.StartInfo.FileName = "ipconfig";

            // we don't want this to output the original command
            pProcess.StartInfo.UseShellExecute = false;

            //Set output of program to be written to process output stream
            pProcess.StartInfo.RedirectStandardOutput = true;

            //Start the process

            //Get program output
            string strOutput = pProcess.StandardOutput.ReadToEnd();

            // split it by line
            string[] ourText = strOutput.Split('\n');


            foreach (string line in ourText)
                if (line.Contains("IP"))
                    Console.WriteLine(line + "\n");
			// close the process

Compile this file from the command line:

csc ip.cs

and it’s ready!


These files both provide a simple executable to output your ip address where you can read it quickly. If you have multiple adapters they will show up as well.

I hope this helps!
