One of the most efficient ways to limit the access to your website is to block the IP addresses of individuals that must not be able to open it. There are various good reasons to do that. As an example, you may want a specific individual not to be able to see your Internet site, or you may limit the access for a whole nation. You can even block IP addresses in case you notice that there are lots of Internet browser requests from them, if a large number of spam comments are left on your Internet sites or if a script login page has been loaded a large number of times. In any of these scenarios, the traffic is more than likely fake and has been generated by an automatic bot, so you may safely block any shady IP address, to be on the safe side. That way, you'll also steer clear of the prospect of your hosting server getting overloaded by many fake requests.
