Lower TTLs for NS and DS records in reverse DNS delegations
by Anand Buddhdev 03 Dec '21

03 Dec '21

Dear colleagues, Users may request reverse DNS delegation by creating "domain" objects in the RIPE Database. Such domain objects must contain "nserver" attributes to specify the name servers for a reverse DNS zone, and may contain "ds-rdata" attributes, to specify delegation signer (DS) records. When the RIPE NCC publishes these records in the appropriate parent zones, the Time to Live (TTL) of all these records is set at 172800 (two days). The TTL of delegation NS records may be overridden by the TTL of NS records from a zone's apex. Alternatively, many large resolvers ignore the TTL values of NS records and cap them at much lower values such as 21600. Finally, there is no way for a zone operator to change the TTL of a DS record, which is only present in a parent zone. Long TTLs can cause problems for users when they want to change their name servers or perform DNSSEC key roll-overs. A long TTL on a DS record is especially harmful when a user needs to do a key roll-over in an emergency. We propose to lower, in the first quarter of 2022, the TTL on NS records to 86400 and on DS records to 3600. We welcome feedback or discussion about this, ideally via the DNS Working Group mailing list. If you prefer to send your feedback directly to us, you can email dns(a)ripe.net. Regards, Anand Buddhdev RIPE NCC

Dear all, The deadline for DNS WG co-chair candidate volunteering is now over. I am happy to announce that we have two great candidates. The period to express support for your preferred candidate(s) starts now and runs until November 24th 2021. Shane Kerr and myself, as continuing wg co-chairs hope to announce consensus at the DNS WG session during RIPE 83 Below find the candidate names and a few words from each =============================================================== Moritz Müller ----------------- Dear RIPE WG, I would like to volunteer to become a DNS working group co-chair. As a frequent participant and an occasional presenter at this working group I would like to help making sure that the program of the working group meetings continues to stay interesting and relevant. I'm working for the research department of the Dutch ccTLD operator SIDN for more than 6 years. There, amongst other topics, I have been studying different aspects of DNSSEC and domain name abuse. Also, I'm a guest researcher at the University of Twente in the Design and Analysis of Communication Systems group (DACS). I believe that my experience working in industry and academia will help me finding and selecting speakers that provide relevant and novel insights to the working group members. Please feel free to contact me in case of any questions or if you would like to get to know me a bit better. Email: moritz.muller(a)sidn.nl =============================================================== Brett Carr —————— Over the past 20 plus years I have worked with DNS holding a variety of industry related roles ranging from working for a global ISP to working at RIPE NCC (Leading the team who run K Root). I have also worked at ICANN (Assisting with the GTLD Programme) and for the last 13 years Nominet, helping to keep .uk safe and stable. I have designed, deployed and managed DNS and DNSSEC implementations both small and large and have been responsible for designing and operating Nominet’s GTLD DNS/DNSSEC Platform which has now grown to operating 80 TLDs. I am an experienced leader having led various engineering teams across operations during my time at Nominet. I have and continue to enjoy playing an active role in the DNS Community, giving presentations at OARC, RIPE and ICANN amongst others. I’m currently serving as the Vice Chair of the CSC at ICANN, I am an active member of the ICANN TLD Ops steering committee and have been a member of the OARC PC for the past year. I would relish the challenge of working with the other chairs to bring some fresh ideas to the DNS-WG. =============================================================== Regards, see you soon, Joao on behalf of the DNS WG co-chairs

I'll be giving an update on DNS4EU on my weekly encrypted DNS call next Monday and will cover the points in the presentation at the HLIG meeting yesterday. I've invited the Commission team to join but can't guarantee that they will be on the call at the moment. Please email me directly if you don't currently attend the calls and would like an invitation - they take place every Monday at 16:00 UTC. Recordings of past calls are accessible at https://419.consulting/encrypted-dns.

Message-ID: <8E01ADB6-5AF2-4EDB-BB89-BEA4E4C31EFC(a)ripe.net> Content-Type: text/plain; charset="utf-8" Hi Hank, all, A number of us from the RIPE NCC (and others from the RIPE community) were in yesterday?s HLIG meeting. There was a presentation on DNS4EU, and I?m trying to track down those slides and whether they?ll be made public - at this point, there?s nothing on the site, but we?ll certainly share any slides (or a public report on the meeting) when they become available. The significant output was that the Commission expects to have a public Call for Proposals around the end of this year, as part of Connecting Europe Facility (CEF 2) programme, for an EU-governed public DNS resolver service. Obviously the CfP will contain more detail when it is made public. This is also in line with the Commission?s statement back in June 2021 in section 1.6 of this document: https://data.consilium.europa.eu/doc/document/ST-10137-2021-ADD-1/en/pdf In the meantime, others may be able to share insights, and we will share links to public documents from yesterday?s session as we obtain them. Cheers Chris
