One of the most effective ways to restrict the access to your Internet site is to block the IP addresses of those that must not be able to open it. There are various reasons to do this. For example, 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 can even block IP addresses if you discover that there are too many Internet browser requests from them, if many spam comments are left on your sites or if a script login page has been loaded a lot of times. In each of these cases, the traffic is more than likely fake and has been created by an automatic bot, so you could safely block any questionable IP address, so as to be on the safe side. This way, you'll also steer clear of the chance of your server getting overloaded by a lot of fake requests.
