In august 2017 the ICANN Root Server System Advisory Committee (RSSAC) published a “Technical Analysis of the Naming Scheme Used For Individual Root Servers”, looking into different naming schemes for the root servers (including DNSSEC signing of the set) and doing risk analysis on them, as RSSAC028.

The first recommendation in the report: “Stick with the current scheme”. The report also recommends further study of feasibility and risk factors of the different naming schemes discussed in the document.

Since September a consortium of people from NLnet Labs and SIDN Labs is performing one of the recommended followup studies to look into resolver behaviour for the different naming schemes. This involved extending a resolver testbed developed at ICANN to simulate as much as possible the different root servers as much as possible - which in turn involved a survey for the root server operators, to collect the different OSes and software in use by the root servers..

This lightning talk will showcase this work and talk about the challenges we had and have doing the study.
