Recommendation DescriptionCurrent Phase
Recommendation
1
1AThe
Root Zone Evolution Review Committee (RZERC) is pleased to respond to the Board's request for advice on ICANN’s “Updated Plan for Continuing the Root KSK Rollover” per its resolution 2018.05.13.09. The RZERC has confidence in the assessments made by SSAC, RSSAC, the root zone management partners, and ICANN's Office of the Chief Technology Officer (OCTO). At this time, the RZERC does not have significant additional advice to add to what these activities have already provided. Additionally, the RZERC is not aware of any reason for not resuming the updated plan for continuing the root KSK rollover.
RZERC recommends that ICANN org conduct the further studies called for in Recommendation 2 of RSSAC028 and focus on these aspects of the research: Revisit the options and consequences of having signed root zone name server data.

Recommendation 1B

The RZERC recommends that ICANN org conduct the further studies called for in Recommendation 2 of RSSAC028 and focus on these aspects of the research: Understand and document the behavior of authoritative DNS software currently in use by root server operators with respect to a signed priming response. This should include, but not necessarily be limited to, the size of a signed priming response. Would this result in a lot of UDP fragmentation? Should root server operators expect to see a significant increase in TCP traffic?

Recommendation 1CThe RZERC recommends that ICANN org conduct the further studies called for in Recommendation 2 of RSSAC028 and focus on these aspects of the research: Understand and document the behavior of recursive name servers with respect to validating signed priming responses. Do they validate and detect incorrect data? What fraction of priming queries today have the DO bit set?

Recommendation 2AThe RZERC recommends that ICANN org further explore the cost / benefit tradeoffs and risks of signed root zone name server data.
