In case you operate a website, then it can essentially be accessed by anybody in the world who has an internet connection. However, there are times when you might need to geographically restrict the type of people visiting your website based on their geographic location. Maybe you run a private or personal website, or you have a local repair shop within a small town. In such cases, you do not require indexes from other countries waste precious bandwidth on your servicer. As such, the following are methods through which you can set up a geolocation database for blocking countries.
Use Apache Modules
Instead of using a .htaccess file that is tedious to fill up with restricted IPs, you can instead opt to install a C library in addition to an Apache module to make the task easier. DBIP provides one of the best IP geolocation databases for looking up IP addresses. This database is known as the DB-IP Lite databases. What’s more, it receives monthly updates. Install one of their APIs and use their database to handle your traffic accordingly.
Block The Application Layer
There are various APIs you can use to block content at the application layer. Some of them include the .NET, Perl or PHP APIs. these can assist you in setting Geo-location criteria right within the application. This process might be a necessity in case you need to decide on factors such as displaying different pages for different languages or countries, or if you have totally different offerings for various regions and need to alter the base mechanism of your application in a particular manner. Nevertheless, this is a very slow method of Geo restriction, since you must manually conduct an IP lookup and verify before your code can completely compile a page.
This method is used for blocking content at the firewall level. Using Routing Tables would naturally reduce the workload from your server application e.g. Apache. Likewise, you will not have to individually undertake the coding at the application level. Nevertheless, attempting to keep the routing tables fully updated with correct IP addresses can be a maintenance nightmare. Therefore, this method is usually preferable when dealing with a few IPs. it should also not be used for locked down servers or shared hosting whereby admins cannot perform mass updates or access routing programs. But one good thing is that any blocked IP is not just blocked from web traffic on port 80. It is blocked from accessing your server through whichever port.
This is a web application firewall for IIS, Nginx and Apache. ModSecurity aims at protecting a system against various types of attacks and also allows for the monitoring of HTTP traffic, real-time analysis, and logging. It can be installed and configured on a bare server, but this needs a skilled administrator. However, in case your host avails a WebHostManager (WHM), you can make the requisite configurations from the WHM interface. While using the WHM, you first need to download the legacy database of a country. At DB-IP, you can find the best IP geolocation database for this purpose.
Utilize a proxy service for your domain
This process entails the masking of a domain through a proxy service which deals with all the source traffic prior to forwarding them to your server. Proxy services operate through DNS protocols, and in most cases, you only require to alter the DNS settings in order to use them. One renown proxy service is CloudFlare. It has the best IP geolocation database that can be used for blocking unwanted traffic.
While using a proxy service, your site will function through the proxy, and you also gain security add-ons, content delivery and other controls.
The above are just a few of the ways through which you can control access to your site by blocking countries. Visit DB-IP today at https://db-ip.com/ for the best advice and tips on website access control.
