Asp.net: Get public IP address of visitors

In this article I am going to explain how to get the public IP address of visitors

In the previous post I have explained how to merge two or more datatables in c#using C# and vb.net and how to create image gallery in asp.net.

Description:

Many times we needed the IP address of visitors. To  get the IP address of  visitors use the below given snippets.

Implementation:

C# Code:

protected void Page_Load(object sender, EventArgs e)

    {

string ipaddress;

        ipaddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

        if (ipaddress == "" || ipaddress == null)

            ipaddress = Request.ServerVariables["REMOTE_ADDR"];

        lblipaddress.Text = ipaddress;

}

VB.net Code:

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

        Dim ipaddress As String

        ipaddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR")

        If ipaddress = "" OrElse ipaddress Is Nothing Then

            ipaddress = Request.ServerVariables("REMOTE_ADDR")

        End If

        lblipaddress.Text = ipaddress

    End Sub

Build and run the application. To test it uploads it to server.
