One of the most effective approaches to limit the access to your website is to block the IP addresses of the individuals that should not be able to open it. There are many 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 could limit the access for a whole nation. You can even block IP addresses in case you detect that there are way too many Internet browser requests from them, if many spam comments are left within your Internet sites or if a script login page has been loaded numerous times. In any of these scenarios, the traffic is most probably fake and has been produced by an automatic bot, so you could safely block any suspicious IP address, to be on the safe side. This way, you shall also steer clear of the possibility of your hosting server getting overloaded by way too many fake requests.
