Sometime we need to use IP Address of Client System in our application, just for record or for other purpose..
In this article i will explain how to get  IP Address of the client using asp.net. To get the IP Address of the client in ASP.NET , you can use the property UserHostAddress of the current Request object. The following example shows you how to get the IP Address address of a client.

        HttpRequest request = HttpContext.Current.Request;

        return request.UserHostAddress;

    }

protected void btnIpAddress_Click(object sender, EventArgs e)

    {

        string ipAddress = GetIPAddress();
        Response.Write("IP Address: " + ipAddress);

    }

protected Function GetIPAddress() As String

        Dim request As HttpRequest = HttpContext.Current.Request

        Return request.UserHostAddress

    End Function

Protected Sub btnIpAddress_Click(ByVal sender As Object, ByVal e As System.EventArgs) HandlesbtnIpAddress.Click

        Dim ipAddress As String = GetIPAddress()
        Response.Write("IP Address: " & ipAddress)
