CZ.NIC has quite a long tradition of acquiring, processing and publishing data about the operation of authoritative DNS servers, public resolver ODVR, CZ domain register and mojeID service. Whilst previous (and still active) web pages with statistics offered many graphs and extensive options for setting their parameters, they tended to evoke the refrain from the popular Czech song by Zdeněk Svěrák and Jaroslav Uhlíř: “Statistics is boring, albeit having valuable data …”. One of very few positive outcomes of the covid pandemic was, thanks to the efforts of Johns Hopkins University and many other institutions, a considerably raised standard of statistical visualisations that our old statistics certainly don’t fulfil.
Survey results: DNS resolvers’ configuration
Contemporary DNS software is very complex. Vendors and development teams lack feedback about the features that are actually in use. Our survey aimed to obtain such information from users. The results are described in this article. Users and administrators of DNS resolvers from any vendor were invited to participate in this survey. This post follows the article “Survey: How do you configure DNS resolvers?”.
