Abstract: 

There is a need to catalogue and treat the predominant emerging tensions that impact the public interest, introduced by DNS privacy measures. One of the most recent examples is that when internet protocols like DNS-over-HTTPS made DNS lookup more private for the user, it had an initial adverse affect on internet measurements, it consolidated provision to large ISPs and service providers, it made abuse mitigation harder, it broke browser add-ons for accessibility tools, and it provoked internet shutdowns and censorship measures. And yet, it is in the public interest and the interest of the internet protocol standards community to continue pushing privacy-respecting protocols. The panel is a call to the community to properly research tensions as they emerge, informed as much as possible by the effects on end users. A draft paper summarizes these emerging tensions in the case of Private DNS and points towards better mitigations in the public interest.
