DNS over TLS (DoT) has been gaining attention, primarily as a means of communication between stub resolver and recursive resolver. There have also been discussions and experiments involving the use of DoT to communicate with authoritative nameservers (Authoritative DNS over TLS or “ADoT”), including communication between recursive and authoritative resolvers with a focus on the lower levels of the DNS hierarchy.

In this presentation, we will discuss operational concerns that need to be addressed prior to ADoT’s deployment at scale by DNS operators in order to maintain the stability and resilience of the global DNS. This presentation will also discuss suggested next steps to advance the operator community’s understanding of ADoT’s operational impact.
