One of the most effective ways to limit the access to your Internet site is to block the IP addresses of those that shouldn't be able to open it. There are numerous good reasons to do that. As an illustration, you may want a certain individual not to be able to see your site, or you can limit the access for an entire country. You could also block IP addresses in case you discover that there are too many web 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 a lot of times. In any of these cases, the traffic is almost certainly fake and has been created by an automatic bot, so you may safely block any suspicious IP address, so as to be on the safe side. This way, you will also stay away from the chance of your server getting overloaded by way too many fake requests.
