How does “Block This! – FREE” work?
Learn how we block ads on your Android device.
Block This! was started in June 2015 by Sava Georgiev – a passionate developer and security researcher with the only purpose of reducing spam and malware on the web.
The idea was to create an Android app which is able to block as much as possible of the junk on the internet namely ads, spam & malware, phishing sites, etc. while being 100% secure, does not log or collect user data, does not put heavy load on your mobile device and works on both rooted and non rooted phones.
In order to do this we had to get out of the box of traditional ad blocking software and go one step further. We had the brilliant idea to incorporate an old and forgotten approach for blocking internet requests – blocking by DNS.
In July 2015 we set up our first higly scalable DNS (Domain Name Server) servers and our first tests immediately showed astonishing ad blocking success. Many ads were blocked and in some cases browsing speed was improved.
But what exactly does DNS do? In short a “Domain Name Server” is used to determine where on the network (internet) is a domain name located. For example, when your borwser asks a DNS, where “https://block-this.com” is, it will normally tell your browser that this site is located at the IP Address: 188.8.131.52. Your browser then goes to that IP and fetches the website so that you can view it. Now imagine your browser requests a well known advertisement network like ads.example.com. Your browser once again asks the DNS – “Where is ads.example.com located?”. In case you are using our DNS, the answer would be 127.0.0.1 which is your local address and effectively means – “Do not load anything”.
Your browser or your andrid app app will then follow these instructions, thus not loading any ads or malware while saving you a lot of traffic, extending your monthly mobile data allowance by up to 25%.
The only problem with this approach is, that for Android there are strict rules about who and how DNS can be changed. Normally changing the DNS directly needs ROOT access (i.e. your android device to be rooted). In order to work around this issue, “Block This” for Android creates, what we call a local VPN (Virtual Private Network) and all of your apps/browser traffic is routed through this VPN. This VPN is carefully configured to only modify the DNS settings of your network, while preserving your internet speed and not sending out any traffic to external VPN servers.
