) has launched a unique new ad blocking service for Android users. The new service takes advantage of the Private DNS feature introduced in Android 9 to give users full ad blocking without requiring the installation of an app or the use of a VPN or proxy. Users instead receive a unique URL which they then set as their Private DNS provider in Android’s network settings. With this easy one-step setup users can enjoy ad and online tracker blocking for everything from browsing the internet with whatever browser they choose, to catching up on the news with their favorite app, to anything else. And best of all, blockerDNS works for both WiFi and mobile internet.
blockerDNS’s primary mission is privacy online. And to that effect, there is ZERO logging of DNS requests. In addition, outside of the basics needed for setting up a monthly subscription with our payment processor Stripe, there is NO other collection of any personal user data. We don’t even maintain our own username and password database and instead have users log in with their Google account, from which we simply access their email address for basic account communication. With consumers increasingly focusing on their internet privacy and the collection of their data, blockerDNS is the absolute easiest way to clamp down on online tracking by marketers and ad networks.
Based in the US, blockerDNS is a modest one-man operation that grew out of an ad blocking DNS over TLS system set up by the owner, Tambe Barsbay, for personal use after growing frustration with other methods that involved VPNs or proxies or extra overhead in the form of apps that were essentially alternative browsers. All aspects of the service, from the TLS tunneling of DNS requests, to the user authentication system (detailed below), to the constantly maintained and updated blocking database, were developed by the owner.
DNS over TLS, the protocol behind Android’s new Private DNS feature, inherently has no user authentication mechanism. blockerDNS’s creative solution to this is that, after signing up, users are given a unique URL to be entered into Android’s Private DNS setting, with the first part of the URL serving as their username. For example, a user may get the URL asdfjkl.blockerdns.com, with “asdfjkl” being their user id. blockerDNS only responds to requests made through valid URLs. Requests through URLs with invalid user ids are simply dropped and will not work.
