Using below code you can fetch User's system IP-Address.

The Problem

Sometime you want to fetch user's IP-Address for monitoring purpose. You can easily get it from current HTTP request. Let's see how to do this.

A quick solution

Simply put this code in your code. Below example useHttpContext.Current.Request to get Current HTTP request.

You can find HttpContext.Current.Request in System.Web namespace.


    public class Utility
        public string GetSystemIPAddress()
            return HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];



Let's call this method.

    class Program
        static void Main(string[] args)
            Console.WriteLine("System IP-Address is:" + new Utility().GetSystemIPAddress());

Hope this can help you.
