Changes to Time-to-Live (TTL) values in reverse DNS zones
by Anand Buddhdev 22 Apr '22

22 Apr '22

Dear colleagues, In 2021, we announced a plan to change the time-to-live (TTL) values in the reverse DNS zones that we maintain. You may view the announcement here: https://www.ripe.net/ripe/mail/archives/dns-wg/2021-November/003928.html Many members of the community expressed support for our proposal. Therefore, we are going to make these changes next week on Wednesday 20 April. We will lower the TTL of NS records to 86400 (1 day) and that of DS records to 3600 (1 hour). Note that the TTL of records imported from other Regional Internet Registries (RIRs) will not be affected. Those records will be imported with the TTLs as published by the origin RIR. Regards, Anand Buddhdev RIPE NCC

New on RIPE Labs: Detecting DNS Root Manipulation
by Alun Davies 19 Apr '22

19 Apr '22

Dear colleagues, In 2021, when reports emerged that hosts in Mexico were unable to reach whatsapp.net, it was determined that middleboxes were to blame. These devices were intercepting the queries to the root instance hosted in China and sending a bogus reply. Taking this as their starting point, Qasim Lone and colleagues have been investigating the prevalence of middleboxes using RIPE Atlas: https://labs.ripe.net/author/qasim-lone/detecting-dns-root-manipulation/ Best regards, Alun Davies RIPE Labs Editor RIPE NCC

Tomorrow is the revised deadline for responses to the European Commission's DNS4EU Call for Proposals. I don't have the impression that there will be a large number of responses from the industry, does anyone have a different perspective? Andrew

Survey on DNS resolver operations and DNSSEC
by Moritz Müller 21 Mar '22

21 Mar '22

*co-chair hat off* Hi everyone, The DNS Security Extensions (DNSSEC) add integrity and authenticity to the Domain Name System (DNS). Now, more than 17 years after their standardization, we would like to hear from DNS recursive resolver operators about their experience with DNSSEC. For this reason, we have set up a short survey. It’s directed mainly towards organisations that run a recursive resolver. Filling out the survey should take roughly 5 to 10 minutes. https://forms.gle/FxTD9FofaogdvLqcA (link directs to Google Forms) This survey is carried out by SIDN Labs (https://sidnlabs.nl) and by the Swedish Internet Foundation (https://internetstiftelsen.se/en/) You can contact us via email: moritz.muller(a)sidn.nl Please excuse us, if you have received this email via different mailing lists. — Moritz Müller Research Engineer at SIDN Labs

Last call and final reminder for nominations to the 2022 Rob Blokzijl Award
by Carsten Schiefner 14 Mar '22

14 Mar '22

[Apologies for cross-posting to various RIPE lists] Dear DNS WG members - this is the last call and final reminder for nominations to the 2022 Rob Blokzijl Award that will be accepted until this Friday, 18th March, at 23:59 UTC. In seeking nominations for this prestigious award, which was created to celebrate Rob's contributions to the development of the Internet, the Award Committee (https://rob-blokzijl-foundation.org/2021/11/22/2022-award-committee/) is interested to receive nominations of those who have reflected Rob's approach in either a technical or operational capacity. Please give some consideration to nominating individuals - but also teams and groups of people! - in your own community and/or the wider industry in the RIPE region who, in your opinion, deserve to be recognised for their work to make the internet and/or internet community better. To specifically have this emphasised again after some according queries: nominations of teams and groups of people are very well possible and wished for as well in case their collective work would match the criteria of the call as laid out! The Award Committee is particularly interested to receive nominations of contributors who, in addition to their own contributions, have also supported and enabled others anywhere in the world. Also, the Award Committee would like to encourage those making nominations to consider not only the community members in the later stages of their careers or who are widely known but also those who may have contributed greatly in the springtime of their career or discreetly for the greater good or who may be considered to be part of an unrepresented group. And last but not least: those of you who previously have made a nomination other than Wilfried Woeber, the 2018 awardee, may want to consider resubmitting a nomination. The complete details of the call and the nomination process can be found at: https://rob-blokzijl-foundation.org/2021/11/25/call-for-nominations-2022/ Best wishes and kind regards Carsten (on behalf of the Award Committee)

follow up of "Update RIPE's DNS Zonemaster"
by Nick Cao 22 Feb '22

22 Feb '22

When doing a DNSSEC algorithm rollover from ecdsap256sha256 to ed25519 today, I got the error 'Unknown cryptographic algorithm' when updating ds-rdata field. A quick google search led me to https://www.ripe.net/ripe/mail/archives/dns-wg/2021-January/003796.html, which dates back to more than a year ago. It seems that the zonemaster deployment has not been updated to day, thus I would like to ask about the current progress.
