Save User's IPAddress and Time of Visit in database in ASP.Net

This way

C#:

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        this.StoreVisitorIPDetails();
    }
}

private void StoreVisitorIPDetails()
{
    string ipAddress;
    // Gets Client IP Address
    ipAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (ipAddress == "" || ipAddress == null)
        ipAddress = Request.ServerVariables["REMOTE_ADDR"];
        
        
    string strConnString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    SqlConnection con = new SqlConnection(strConnString);

    SqlCommand cmd = new SqlCommand("StoreIPAddressDetails");
    cmd.CommandType = CommandType.StoredProcedure;

    cmd.Parameters.AddWithValue("@IPAddress", ipAddress);    

    cmd.Connection = con;
    con.Open();

    cmd.ExecuteNonQuery();

    con.Close();
    con.Dispose();
}

SQL:

CREATE TABLE [dbo].[StoreIPAddress](
	[Id] [int] IDENTITY(1,1) NOT NULL,
	[IpAddress] [varchar](50) NULL,
	[VisitedDate] [datetime] NULL
) ON [PRIMARY]

GO

Stored Procedure:

CREATE PROCEDURE StoreIPAddressDetails
	@IPAddress VARCHAR(50)
AS
BEGIN
	INSERT INTO StoreIPAddress
			   (IpAddress
			   ,VisitedDate)
	    VALUES(@IPAddress
			   ,GETDATE())
END
