New c-nsp, j-nsp, a-nsp, etc mailing lists
by Drew Weaver 10 Aug '25

10 Aug '25

I was a big fan of the *-nsp(a)puck.nether.net<mailto:*-nsp@puck.nether.net> mailing lists that now seem to be completely gone without any indication of whether or when they might return. I've been considering just setting up new ones. Please email me off-list if you think this might be useful. Thanks, -Drew

Source Address Validation (SAV) Deployment and Operational Practices
by Amir Herzberg 04 Aug '25

04 Aug '25

Friends: uRPF and similar SAV techniques have been around for long, with new variants recently/being standardized by the IETF (eFP-uRPF, BAR-SAV). We have done simulations to evaluate the impacts of these variants. To improve our research, we set up a short, quick survey for network managers and administrators of ASNs. In this study, we want to understand the deployment challenges, operational considerations, adoption trends and operator concerns in this area. It would be amazing if you could respond to the survey, available in: https://forms.gle/3rRtCTa2xk217tyd6 We really appreciate your help. The form also contains an option to leave your email for us to send you our research results (paper, simulations, survey). Thanks a lot!! -- Amir Herzberg Comcast professor of Security Innovations, Computer Science and Engineering, University of Connecticut Homepage: https://sites.google.com/site/amirherzberg/home `Applied Introduction to Cryptography and Cybersecurity' textbook: https://sites.google.com/site/amirherzberg/crypto-cyber-book

GoDaddy deleting most ancillary registration contact information
by Mel Beckman 29 Jul '25

29 Jul '25

I just received this notice through one of my clients. Due to recent changes in the Registration Data Policy (Addendum II), we're updating how Organization Name info is displayed in WHOIS/RDDS: Currently, we collect Registrant, Administrative, Billing, and Technical contacts. Going forward, we'll collect the minimum data required by each domain registry. Most registries will be moving to the minimum data set, so Technical, Administrative, and Billing contacts will no longer be collected or displayed in WhoIs/RDDS. On or after August 21, 2025, we'll delete extra contact data and the registrant fax number from our systems unless the registry specifically requires that data. There is no action needed from you for the above changes. Where your Registrant contact data contains a populated Organization field, this will not be displayed in the Whois/RDDS. First, this seems like awfully short notice. Second, although I remember reading something about this a month ago having to do with GDPR, I didn’t realize it would result in the deletion of existing data in North America. For domains I manage, I have an opportunity, however brief, to collect this information for future use. However, I’m surprised that this is happening to domains registered in North America. I would think it would conflict with ICANN requirements. Has anybody else got ideas on the impact of this going forward? I’m not in the domain resale business, but I am in the business of troubleshooting network problems. :-) -mel

OARC 45 Call for Contributions
by Willem Toorop 28 Jul '25

28 Jul '25

This workshop will be a hybrid event. Date - 7-8 October 2025 Location - Stockholm, Sweden Time - Approx 10:00 CEST (08:00 UTC) - 17:00 CEST (15:00 UTC) Adjacent to Netnod Tech Meeting 2025 (9 October 2025) (https://www.netnod.se/netnod-tech-meeting-2025) Deadline for Submissions - 2025-07-29 23:59 UTC https://indico.dns-oarc.net/event/55/abstracts/ All DNS-related subjects and discussion topics are welcome although we're particularly keen to hear more about operational and security related experiences, best practices and practical advice; both for newcomers to the DNS arena and those who have been around for longer who want to learn more about new features and opportunities to improve resilience, security and privacy. (These topics we think will complement the usual high-quality data-based research submissions we always hope to receive!) If you have something interesting to share with the community that lies outside of the focus above, please don't be put off - if it's good, we'll be happy to include it. If you'd like to offer a talk, but are not quite sure what to pick, here's a non-exhaustive list of ideas: 1. *Operations & Deployment* * Configuration management, deployment processes, and interoperability experiences. * Tools, tips, and making effective use of DNS software features. 2. *Performance, Resilience & Scaling* * Provisioning, load-balancing, and planning for resilience. * DNS performance management, efficiency improvements, and metrics. * Monitoring infrastructure: log pipelines, analytics, and anomaly detection. 3. *Security, Privacy & Policy* 1. DoS attacks, DNS abuse, DNSSEC signing and validation. 2. Privacy considerations, for example: encrypted transport, qname minimization, data anonymization. 3. Relevant global and regional policies, legislation, and compliance. 4. *Research & Innovation* 1. Data-driven testing, measurement, and analysis. 2. New protocols, protocol extensions, and next-generation namespace management. 5. *Lessons & Learnings* 1. Outage experiences, recovery stories, and cautionary tales For further details please see https://www.dns-oarc.net/oarc45 Willem Toorop, for the DNS-OARC Programme Committee

Hi, Could anyone tell me what is the level of UDP traffic on the internet? and among UDP traffic, which percentage is not responsive to congestion (i.e. classic UDP without including responsive flows to congestion such as QUIC and RTP)? Thanks, Djamel
