One of the most effective methods 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 numerous good reasons to do this. For instance, you may want a certain person not to be able to see your website, or you can limit the access for an entire state. You can also block IP addresses in case you detect that there are too many Internet browser requests from them, if a huge number of spam comments are left on your Internet sites or if a script login page has been loaded a lot of times. In any of these cases, the traffic is almost certainly fake and has been generated by an automatic bot, so you can safely block any shady IP address, to be on the safe side. Thus, you will also stay away from the prospect of your hosting server getting overloaded by a lot of fake requests.
