Status Update, December, 2009

This is the first of a series of technical status updates intended to inform a technical audience on the progress of deploying DNSSEC in the root zone of the DNS.


Details of the project, including documentation published to date, can be found at

We’d like to hear from you. If you have feedback for us, please send it to


This project involves the creation of a large volume of documentation, individual components of which will be released as they have completed internal review. The following documents are expected to be released as drafts in early 2010:

  • Root Zone DNSSEC Deployment Plan
  • Root Zone Trust Anchor Publication


Several root server operators have started testing a lightweight packet capture tool designed to provide a full record of priming queries received over the period covering DNSSEC deployment in the root zone. We hope this data collection will be in full production on all root servers before the end of December, providing baseline data which will allow the reaction of the system as a whole to deployment events to be observed.

On 2009-12-01 the first pre-production KSR exchange between ICANN and VeriSign and the signing of the root zone within VeriSign’s production infrastructure commenced. The signing, validation, measurement and monitoring infrastructure will now be subject to full internal testing.

(Please note that this schedule is tentative and subject to change based on testing results or other unforeseen factors.)
