OARC 45 Call for Contributions 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 DoS attacks, DNS abuse, DNSSEC signing and validation. Privacy considerations, for example: encrypted transport, qname minimization, data anonymization. Relevant global and regional policies, legislation, and compliance. 4. Research & Innovation Data-driven testing, measurement, and analysis. New protocols, protocol extensions, and next-generation namespace management. 5. Lessons & Learnings Outage experiences, recovery stories, and cautionary tales For further details please see https://www.dns-oarc.net/oarc45 Raffaele Sommese, for the DNS-OARC Programme Committee
