One of the most efficient approaches to restrict the access to your site is to block the IP addresses of individuals which mustn't be able to open it. There are numerous reasons why you should do that. For example, you may want a particular individual not to be able to see your Internet site, or you may restrict the access for a whole country. You can also block IP addresses if you detect that there are way too many browser requests from them, if a lot of spam comments are left on your Internet sites or if a script login page has been loaded a large number of times. In any of these situations, the traffic is more than likely fake and has been generated by an automatic bot, so you may safely block any questionable IP address, so as to be on the safe side. That way, you shall also steer clear of the possibility of your web server getting overloaded by too many fake requests.
