BGPVIZ2 – Looking for Community Feedback
by Cuenta Uno 31 Oct '26

31 Oct '26

Hi everyone, I've been developing BGPVIZ2, a web-based tool for visualizing historical BGP routing behavior using Route Views data. It provides interactive AS path visualizations, prefix visibility timelines, and automatic detection of routing changes and potential anomalies. I'd really appreciate it if members of the community could give it a try and share their feedback, especially regarding accuracy, usability, and potential improvements. https://routeviews.cloud/ Thanks in advance for your time and feedback!

User Study: AI Assistance at IT Help Desks
by Jonas Wessner 27 Oct '26

27 Oct '26

Dear RIPE Community, we invite you to take part in our study on *AI Assistance at IT Help Desks*. Every company and university has a team of IT specialists who take care of technical problems of their users. Often, these teams are overloaded by inquiries so that users must wait several days for a response. In this user study, we explore whether AI suggestions can help with processing help desk tickets and emails related to network access control. The insights of this study will allow for designing useful and data-proven AI-assisted user interfaces to support staff at computing centers and help them to solve problems and get back to users faster. The study takes about 20-30 minutes and is completely anonymous. 🔗 Study link: https://ibac-study.lxd-vs.uni-ulm.de We are aiming for a total of 300 participants. So please share this study link with others. We are particularly interested in participants with a background in network administration or computer science, but we also welcome in participants without technical background. Thank you for your time and support!

[CfP] NewGeo 2026 - New Directions in IP Geolocation Workshop (co-located with IMC 2026)
by Oliver Gasser 07 Aug '26

07 Aug '26

================================================================ CALL FOR PAPERS NewGeo 2026 New Directions in IP Geolocation Workshop Co-located with ACM IMC 2026 Karlsruhe, Germany - Monday, October 12, 2026 https://newgeo-workshop.github.io/ ================================================================ IP geolocation -- the ability for a third party to map an IPv4 or IPv6 address to its physical location -- is a foundational building block for Internet services, network management and operations, policy enforcement, security, and regulatory compliance. As the accuracy and coverage of IP geolocation is becoming increasingly critical, not only are the underlying mechanisms insufficiently understood, they are increasingly challenged by architectural shifts in the Internet and evolving services. The December 2025 IAB Workshop on IP Address Geolocation surfaced fundamental open questions about accuracy and integrity, the limitations of self-publishing mechanisms such as geofeeds (RFC 8805), and architectural tensions between passive location inference and evolving privacy expectations, and its report explicitly recommends further research. At the same time, IPv6 adoption, VPNs and relay services, CGNAT, satellite-based access, and regulatory frameworks such as the EU's GDPR and Digital Services Act all challenge current geolocation assumptions. The NewGeo workshop seeks to provide a focused forum on IP geolocation to consolidate findings, compare methodologies, benchmark datasets, build shared infrastructure, bring together academia and industry, and discuss common challenges and future research directions. NewGeo 2026 invites original research contributions that advance our understanding of IP geolocation. IMPORTANT DATES --------------- Paper submission deadline: September 6, 2026 Notification of acceptance: September 20, 2026 Camera-ready deadline: October 4, 2026 Workshop: October 12, 2026 All deadlines are 23:59 AoE (UTC-12). TOPICS OF INTEREST ------------------ We solicit short papers on topics including, but not limited to: * Measurement and analysis of IP geolocation databases (e.g., geofeeds) * Novel active and passive geolocation techniques that accommodate emerging Internet architectures (VPNs, relays, cellular and mobile, IPv6, CGNAT, address sharing, etc.) * Geolocation challenges and approaches for satellite-based and deep space Internet access * Ground truth collection methodologies and benchmark datasets * Artificial Intelligence-based approaches for IP geolocation, validation, or verification * Longitudinal studies of geolocation accuracy and database evolution * Applications and implications of IP geolocation for content delivery, regulatory compliance, fraud detection, and censorship measurement * Privacy implications of IP geolocation and location inference * Reproducibility studies of previously published geolocation measurement work SUBMISSION GUIDELINES --------------------- Submissions must be original work not previously published and not under review elsewhere. Papers should be at most 4 pages in length, excluding references and an optional one-page appendix. Reviewers are not required to read the one-page appendix. Papers must be formatted according to the ACM two-column 10 point font sigconf style: https://www.acm.org/publications/proceedings-template All submissions will undergo double-blind peer review by the program committee, so please anonymize your submission. Authors must adhere to the ACM's author guidelines on the use of Generative AI: https://www.acm.org/publications/policies/frequently-asked-questions Papers violating the submission guidelines will be desk-rejected. Accepted papers will be presented at the workshop, and at least one author of each paper is expected to attend in person. Authors are encouraged to make their measurement data and analysis code available to support reproducibility. Submissions will be handled via HotCRP; the submission URL will be announced on the workshop website: https://newgeo-workshop.github.io/ VENUE AND ATTENDANCE -------------------- NewGeo 2026 takes place on Monday, October 12, 2026, co-located with ACM IMC 2026 in Karlsruhe, Germany. Attendance is handled through the standard IMC 2026 registration process: https://conferences.sigcomm.org/imc/2026/ The workshop welcomes participation from academic researchers, network operators, geolocation data providers, RIR staff, Internet standardization contributors, and policymakers. WORKSHOP CHAIRS --------------- Oliver Gasser (IPinfo) <oliver(a)ipinfo.io> Robert Beverly (San Diego State University) <rbeverly(a)sdsu.edu> For questions, please contact the workshop chairs at oliver(a)ipinfo.io and rbeverly(a)sdsu.edu. ================================================================

RIS bview files 1-3-2026 and 21-5-2026 downloaded after 26-5
by Ties de Kock 30 May '26

30 May '26

Dear colleagues, We have identified a misconfiguration in the pipeline that publishes RIS bview files to data.ris.ripe.net, and are giving early notice. As part of an infrastructure change on 27 May 2026, the publishing pipeline re-copied historical bview files produced after February 2022. This had two effects: * File modification timestamps changed for historical bview files published after February 2022. * Some bview files produced between 1 March 2026 and 21 May 2026 may be incomplete. This affects copies of files downloaded after 26 May 2026. For the incomplete files, the likely impact is that data from some RIS peers may be missing from the affected bviews. The data has not been lost. We have multiple copies available and expect to fully recover the affected files after the weekend. In the meantime, data consumers who rely on file modification timestamps, or who downloaded bview files for 1 March 2026-21 May 2026 after 26 May should take this into account. We apologise for the inconvenience and will update you on the situation early next week. Kind regards, Ties de Kock
