If you see a major increase in the online traffic to your site and in case after you examine the visitor stats it turns out that it comes from locations around the world or from other servers, your Internet site is probably being attacked by an automatic bot. Those pieces of software go through random sites seeking to log in to their admin area using a brute-force attack or to leave spam comments under every article where this kind of an option is made available. Regrettably, that's something quite frequent in recent times, but if you know the IP addresses through which the attacks come, you may block them, so the bots will not be able to access your website in any way. Obviously, you may block IPs even if you allow only people from specific countries to access your website.
IP Blocking in Shared Hosting
If you buy a Linux shared hosting package from us, you will be able to see comprehensive traffic stats for all your websites and if you notice that a lot of the visits to any of them aren't legit, you could block the IP addresses that have produced the most traffic via our IP Blocking tool. The interface is very simple - pick the needed domain or subdomain from a drop-down list, then enter the IP address that you want to block and save the change. All the addresses that you've blacklisted will appear in the same section of the CP, so that you can always remove any of them and allow it to access your website again. You are able to block whole IP ranges using the tool as well - you simply need 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.
