One of the most productive approaches to limit the access to your site is to block the IP addresses of the people which shouldn't be able to open it. There are many reasons why you should do that. For example, you may want a specific individual not to be able to see your Internet site, or you can restrict the access for an entire state. You can even block IP addresses if you detect that there are lots of web browser requests from them, if a large number of spam comments are left within your websites or if a script login page has been loaded many times. In each of these scenarios, the traffic is almost certainly fake and has been produced by an automatic bot, so you could safely block any questionable IP address, to be on the safe side. In this way, you shall also avoid the prospect of your hosting server getting overloaded by too many fake requests.
