One of the most productive approaches to restrict the access to your Internet site is to block the IP addresses of individuals that should not be able to open it. There are several reasons why you should do that. For instance, you may want a certain person not to be able to see your site, or you may limit the access for a whole state. You may also block IP addresses if you notice that there are too many Internet browser requests from them, if a huge number of spam comments are left on your websites or if a script login page has been loaded a large number of times. In each of these cases, the traffic is most probably fake and has been created by an automatic bot, so you may safely block any shady IP address, in order to be on the safe side. Thus, you shall also avoid the possibility of your web server getting overloaded by way too many fake requests.
