Question

我有一个简单的网络应用程序，我需要跟踪访问者。每位访客的信息都存储在下表中：

访客详细信息：

| ID | ComputerName | VisitDate | CountryCode | Platform | Browser | BrowserVersion |

[ComputerName]是vistor的IP地址。

该表包含ipv6记录，这会导致计算访问者数量时出现问题，或者有时会导致令牌错误。

强迫访问者使用ipv4是明智的吗？如果有，怎么样？

Answer 1

void Application_Start(object sender, EventArgs e)
{
    // Code that runs on application startup
    Application["NoOfVisitors"] = 0;
}





void Session_Start(object sender, EventArgs e)
{
    // Code that runs when a new session is started
    Application.Lock();
    Application["NoOfVisitors"] = (int)Application["NoOfVisitors"] + 1;
    Application.UnLock();
}

in .aspx page

<asp:Label runat="server" ID="lbluser" />
in .aspx.cs

protected void Page_Load(object sender, EventArgs e)
{
    lbluser.Text = Application["NoOfVisitors"].ToString();
}

Answer 2

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        RegisterRoutes(RouteTable.Routes);

        WebpageCounter.SaveVisitor(new WebpageVisitor()
        {
            VisitorIP = HttpContext.Current.Request.UserHostAddress,
            VisitedOn = DateTime.Now
        });
    }

Below Code is for IP Address
string ipaddress;
ipaddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (ipaddress == "" || ipaddress == null)
    ipaddress = Request.ServerVariables["REMOTE_ADDR"];

Answer 3

    public string IpAddress()
{
string strIpAddress;
strIpAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (strIpAddress == null)
{
strIpAddress = Request.ServerVariables["REMOTE_ADDR"];
}
return strIpAddress;
}

foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
 { 
if (IPA.AddressFamily.ToString() == "InterNetwork")
 { 
IP4Address = IPA.ToString(); 
break;
 } 
}
