One of the most effective methods to limit the access to your site is to block the IP addresses of individuals which should not be able to open it. There are several good reasons to do that. For instance, you may want a specific individual not to be able to see your site, or you could limit the access for a whole nation. You can even block IP addresses in case you detect that there are lots of browser requests from them, if a large number of spam comments are left in your sites or if a script login page has been loaded many times. In all of these situations, the traffic is more than likely fake and has been produced by an automatic bot, so you can safely block any suspicious IP address, in order to be on the safe side. Thus, you will also steer clear of the chance of your server getting overloaded by many fake requests.
