If you see a large increase in the online traffic to your site and if after you check the visitor stats it turns out that it comes from places across the world or from other web servers, your site is most likely being attacked by an automatic bot. Those pieces of software go through random Internet sites looking to log in to their administration area by using a brute-force attack or to leave spam comments underneath every article where such an option is provided. Regrettably, this is something quite popular nowadays, 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 Internet site in any way. Of course, you'll be able to block IPs even if you allow only people from particular countries to access your website.
IP Blocking in Shared Web Hosting
If you purchase a shared web hosting plan from us, you'll be able to see in depth traffic statistics for all of your sites and if you notice that many of the visits to each of them are not legit, you may block the IP addresses which have generated the most traffic using our IP Blocking tool. The interface is really simple - pick the needed domain or subdomain from a drop-down list, then type in the IP address that you would like to block and save the change. All the addresses which you have blacklisted will appear in the same section of the CP, so you can always remove any one of them and allow it to access your Internet site again. You can block entire IP ranges using the tool too - you just have to leave 1 or 2 octets from the address blank. As an example, entering 1.2.3. will block all 254 IPs from 1.2.3.1 to 1.2.3.255.
