how to block country range ip in ASP.net website-CodePudding

I need to block one IP address or country range IP in asp.net website

Can anyone help me with the code? And how to implement?

CodePudding user response：

There's an example of how you could achieve this in the documentation on the Mircosoft site. https://docs.microsoft.com/en-us/aspnet/core/security/ip-safelist?view=aspnetcore-5.0

This should give you an idea on how to approach your issue and rework it to suit your own needs.

CodePudding user response：

on the global.asax on Application_BeginRequest you can check the ip range and if its on your range to block, then stop the processing there (or redirect them to some other page)

protected void Application_BeginRequest(Object sender, EventArgs e)
{
    // check this -> 
    HttpContext.Current.Request.UserHostAddress with your limits
    // and then 
    
    if(doNotAllow)
    {
        HttpContext.Current.Response.TrySkipIisCustomErrors = true;
        HttpContext.Current.Response.StatusCode = 403;
        HttpContext.Current.Response.End();
        return ;     
    }
}
