ICANN has recently released a design that allows researchers to easily test multiple resolver programs for things such as how they handle DNSSEC trust anchors and how they choose root servers from priming queries. The testbed can include common open-source resolver software, but also handles any resolvers that can be run in a virtual machine such as Windows Server and other proprietary...

The number of queries for the '. NS' RRset received at K.root-servers.net today is around 2000/second. This is much higher than what we would expect from well behaved clients.
Hence we have studied all priming queries received at K for seven consecutive days in July 2017. This work describes the general characteristics of the priming queries
and suggests a classification of client behavior....

The Domain Name System (DNS) is a key part of the infrastructure of
the Internet. Recent discussions have centered on the removal of the
shared DNS resolver and the use of a local full-service resolver
instead. From the viewpoint of the cache mechanism, these discussions
involve removing the shared DNS cache from the Internet. Although the
removal of unnecessary parts from a total system...

RFC7872 pointed to some issues with the use of IPv6 extension headers in the Internet and noted a failure rate of some 20% of tests when directing IPv6 packets with IPv6 extension headers towards authoritative name servers. This is a study of a test of the ability to pass fragmented IPv6 packets in the opposite direction, namely from authoritative name servers towards visible resolvers. This...

Caching resolvers are the backbone of the internet, answering trillion of questions for billions of subscribers every day. Every request is cached until its TTL expires or something else needs to be cached. DNS data researchers often construct queries so they’re not cached, but let’s have a detailed look inside a resolver to see how it reacts to queries from average Joe’s accessing the...
