We built the tool “DNS Resolver Recommender”:
It is a small DoH measurement tool that should catch DNS behavior from the user’s browser. It measures a list of 200+ public DoH resolvers for both cached and uncached domains and recommends the best one for the user. Upon opt-in, we also collect the (anonymized) measurement data for research (see the Privacy Disclosure<https://dns.diic-hpi.org/privacy.html> ). We made every effort to collect only data that maintains privacy. In the future, we also want to release snapshots of our data to the community.
If you release a tool called “DNS Resolver Recommender” you should also include the resolver people are actually using which in most cases is there ISP resolvers. I would always recommend to use those as there usually is the lowest latency between you and the resolver, plus a lot of ISP also started to publish RFC9462 (DDR) upgrade records, so you could even use them via DoH.
