[dns-operations] Domain Name System without Root Servers

[Stephane Bortzmeyer]

Nice paper, for resolver managers and TLD managers: how to get rid of
the root for some TLDs (the system would be opt-in):

https://www.vs.uni-due.de/paper/2017_Wander_Rootless_DNS.pdf

The idea is to reuse priming (RFC 8109). The resolvers would know the
NS and DS resource record sets of TLDs, and use priming to refresh
their knowledge. It works as long as a TLD does not change everything
at once.

The most interesting part of the paper is a survey of the TLD changes
in the last four years: most TLD kept at least one IP address of the
original set during these four years. So, the idea could work.
