One of the most productive approaches to restrict the access to your website is to block the IP addresses of those which shouldn't be able to open it. There are numerous reasons why you should do this. As an example, you may want a certain person not to be able to see your Internet site, or you could limit the access for an entire country. You can even block IP addresses if you discover that there are way too many web browser requests from them, if a huge number of spam comments are left in your Internet sites or if a script login page has been loaded many times. In all of these scenarios, the traffic is almost certainly fake and has been generated by an automatic bot, so you could safely block any shady IP address, so as to be on the safe side. That way, you shall also stay away from the prospect of your web server getting overloaded by way too many fake requests.
