One of the most reliable methods to restrict the access to your Internet site is to block the IP addresses of those which mustn't be able to open it. There are several reasons to do that. For instance, you may want a certain individual not to be able to see your site, or you may restrict the access for a whole country. You can even block IP addresses if you discover that there are too many web browser requests from them, if a large number of spam comments are left in your websites or if a script login page has been loaded a lot of times. In all of these cases, the traffic is most probably fake and has been generated by an automatic bot, so you can safely block any suspicious IP address, so as to be on the safe side. In this way, you'll also steer clear of the possibility of your hosting server getting overloaded by too many fake requests.
