Root DNSSEC

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

The final transition to the DURZ will take place on J-Root, on 2010-05-05 between 1700–1900 UTC.

After that maintenance all root servers will be serving the DURZ, and will generate larger responses to DNS queries that request DNSSEC information.

If you experience technical problems or need to contact technical project staff, please send e-mail to rootsign@icann.org or call the ICANN DNS NOC at +1 310 301 5817, e-mail preferred if possible.

See below for more details.

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

DEPLOYMENT STATUS

The incremental deployment of DNSSEC in the Root Zone is being carried out first by serving a Deliberately Unvalidatable Root Zone (DURZ), and subsequently by a conventionally signed root zone. Discussion of the approach can be found in the document “DNSSEC Deployment for the Root Zone”, as well as in the technical presentations delivered at RIPE, NANOG, IETF and ICANN meetings.

Twelve of the thirteen root servers have already made the transition to the DURZ. No harmful effects have been identified.

The final root server to make the transition, J-Root, will start serving the DURZ in a maintenance window scheduled for 1700–1900 UTC on 2010-05-05.

Initial observations relating to this transition will be presented and discussed at the DNS Working Group meeting at the RIPE meeting in Prague on 2010-05-06.

PLANNED DEPLOYMENT SCHEDULE

Already completed:

• 2010-01-27: L starts to serve DURZ
• 2010-02-10: A starts to serve DURZ
• 2010-03-03: M, I start to serve DURZ
• 2010-03-24: D, K, E start to serve DURZ
• 2010-04-14: B, H, C, G, F start to serve DURZ

To come:

• 2010-05-05: J starts to serve DURZ
• 2010-07-01: Distribution of validatable, production, signed root zone; publication of root zone trust anchor

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

A more detailed DURZ transition timetable with maintenance windows can be found in the document “DNSSEC Deployment for the Root Zone”, the most recent draft of which can be found on the project web page at https://www.co.tt/files/dnssecroot/.
