How to get IP Address of the client using Asp.Net C#,VB ?

IntroductionIn this article i will explain how to read or fetch IP Address of the user i.e. client using asp.net. 

In previous article i explained How to read mac address in asp.net and How to get browser name, version, type, operating system in asp.net and Get Title, Description and Keywords Meta tags from URL in asp.net and Prevent duplicate data entry on page refresh in asp.net and Enable browser javascript in asp.net

Description: Sometimes you may want to get the IP Address of the client in ASP.NET. 
In that case you can use the property "UserHostAddress" of the current Request object or by checking "REMOTE_ADDR" and "HTTP_X_FORWARDED_FOR".  I have mentioned two ways to read user IP Address. You can use any of the two.

Asp.Net C# Code to read IP Address of the client

  protected void Page_Load(object sender, EventArgs e)
    {     
        Response.Write("IP Address: " + GetIPAddress());
        // Response.Write("IP Address: " + GetIPAddress2()); 
    }

    protected string GetIPAddress()
    {
        HttpRequest request = HttpContext.Current.Request;
        return request.UserHostAddress;
    }
    protected string GetIPAddress2()
    {
        string IPAddress = string.Empty;
        IPAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
        if (string.IsNullOrEmpty(IPAddress))
        {
            IPAddress = Request.ServerVariables["REMOTE_ADDR"];
        }
        return IPAddress;
    }


Asp.Net VB Code to read IP Address of the client

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
        Response.Write("IP Address: " & GetIPAddress())
        'Response.Write("IP Address: " & GetIPAddress2())
    End Sub
    Protected Function GetIPAddress() As String
        Dim request As HttpRequest = HttpContext.Current.Request
        Return request.UserHostAddress
    End Function

    Protected Function GetIPAddress2() As String
        Dim IPAddress As String = String.Empty
        IPAddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
        If String.IsNullOrEmpty(IPAddress) Then
            IPAddress = Request.ServerVariables("REMOTE_ADDR")
        End If
        Return IPAddress
    End Function
