One of the most effective approaches to limit the access to your Internet site is to block the IP addresses of individuals that should not be able to open it. There are numerous reasons why you should do this. As an illustration, you may want a certain person not to be able to see your Internet site, or you can limit the access for a whole country. You could also block IP addresses in case you detect that there are too many web 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 all of these situations, the traffic is most probably fake and has been generated by an automatic bot, so you could safely block any questionable IP address, in order to be on the safe side. In this way, you shall also steer clear of the prospect of your server getting overloaded by a lot of fake requests.
