If you see a significant increase in the traffic to your website and in case after you check the visitor statistics it turns out that it comes from places around the world or from other servers, your Internet site is probably being attacked by an automatic bot. Such programs go through random sites trying to log in to their administration area using a brute-force attack or to leave spam comments below every article where this kind of an option is offered. The fact is that, that's something relatively popular these days, but if you know the IP addresses from which the attacks come, you could block them, so the bots won't be able to access your website in any way. Needless to say, you can block IPs even if you allow only people from specific countries to access your website.
IP Blocking in Cloud Website Hosting
If you purchase a Linux cloud website hosting from our company, you shall be able to see detailed traffic statistics for all of your Internet sites and if you notice that a considerable amount of the visits to each of them aren't legitimate, you may block the IP addresses that have produced the most traffic using our IP Blocking tool. The interface is incredibly simple - select the needed domain or subdomain from a drop-down list, then type in the IP address that you want to block and save the change. All of the addresses that you have blacklisted shall appear in the same exact section of the CP, so you can always remove any of them and enable it to access your website again. You could block entire IP ranges using the tool as well - you just need to leave one or two octets from the address blank. For example, entering 1.2.3. will block all 254 IPs from 1.2.3.1 to 1.2.3.255.
