Recently the Quad9 DNS service was launched. Quad9 differentiates from similar services by focusing on security and privacy. One interesting feature is the fact that you can communicate with the service using DNS-over-TLS. This encrypts the communication between your client and the DNS server, safeguarding your privacy.
Last week, the new DNS resolver Quad9 has been announced. It is a public DNS resolver with the additional benefit that it is accessible in a secure way over TLS (RFC 7858). There are plenty of public DNS resolvers, but the link to them is not secure. This allows hijackings, as seen in Turkey, as well as third-party monitoring. The new Quad9 service on the other hand is operated by the not-for-profit Packet Clearing House (PCH), which manages large parts of the DNS infrastructure, and it allows access to the DNS over TLS. This makes it very difficult for third parties to listen in. And it makes it possible to authenticate the resolver.
