Google announced general availability of its Public DNS-over-HTTPS service Wednesday, based on the Internet Engineering Task Force’s RFC 8484 standard. The move is a culmination of three years of Google fine-tuning DNS over HTTPS, otherwise known as DoH.

“Today we are announcing general availability for our standard DoH service. Now our users can resolve DNS using DoH at the dns.google domain with the same anycast addresses (like 8.8.8.8) as regular DNS service, with lower latency from our edge PoPs throughout the world,” wrote Marshall Vale, product manager and Alexander Dupuy, software engineer in a Google Security Blog.

The move is an effort by Google to boost consumer privacy, reduce the threat of man-in-the-middle attacks, and speed up the internet with a new solution for securing domain name server traffic that uses the encrypted HTTPS channel.

The adoption of the RFC 8484 is important. The standard has not yet been ratified by the IETF, but as more internet stakeholders adopt it, the closer it is to formally becoming a DoH standard.
Security and Privacy Concerns
They argue, by routing traffic through a content distribution network management system (such as Cloudflare and others) they are creating new central repositories for DNS queries that could be hacked or used to mine personal identifiable information (PII) data.
In Google’s DoH test its privacy policy states:

“Your client IP address is only logged temporarily (erased within a day or two), but information about ISPs and city/metro-level locations are kept longer for the purpose of making our service faster, better, and more secure.”
