!!! Devo usar DNS criptografado?
DNS criptografado com servidores de terceiros só deve ser usado para contornar o [bloqueio básico de DNS](https://en.wikipedia.org/wiki/DNS_blocking) quando você pode ter certeza de que não haverá nenhuma consequência. DNS encriptada não irá te ajudar a esconder qualquer uma das suas atividades de navegação.
Encrypted DNS with a 3rd party should only be used to get around redirects and basic <a href="https://en.wikipedia.org/wiki/DNS_blocking">DNS blocking</a> when you can be sure there won't be any consequences or you're interested in a provider that does some rudimentary filtering. Encrypted DNS will not help you hide any of your browsing activity.

They also keep and store the database of domains requested in within last 24 hours. "We need this information to identify and block new trackers and threats." "We also log how many times this or that tracker has been blocked. We need this information to remove outdated rules from our filters."
