One of the most efficient methods to limit the access to your website is to block the IP addresses of individuals which must not be able to open it. There are numerous good reasons to do that. For example, you may want a certain individual not to be able to see your Internet site, or you can restrict the access for a whole country. You may also block IP addresses if you discover that there are way too many browser requests from them, if a huge number of spam comments are left on your Internet sites or if a script login page has been loaded many times. In each of these cases, the traffic is more than likely fake and has been generated by an automatic bot, so you may safely block any questionable IP address, so as to be on the safe side. In this way, you'll also avoid the prospect of your hosting server getting overloaded by a lot of fake requests.
