blockerDNS provides a customizable DNS service that, simply put, lets you block content on the internet you don't want to see. By default we block ads and online trackers, but you're in complete control with the option to fine-tune your blocking through customizable blacklists and whitelists, as well as 1-click category blocks that let you easily filter things like adult content or social media. The service is offered via DNS over TLS, DNS over HTTPS and standard DNS.
