Dear colleagues, Sebastian Kappes and colleagues look at how routers that rewrite TTL values can cause traceroute to miss parts of a path and give a misleading picture of how networks are interconnected: https://labs.ripe.net/author/shk/when-traceroutes-lie-how-ttl-jumps-can-giv… Comments and feedback very welcome as always!

by Ulka Athale 01 Sep '26

01 Sep '26

This message is sent on behalf of the Number Resource Organization ----------------------- Recommended Draft RIR Governance Document, Rationale Report, and next steps ----------------------- The Number Resource Organization Executive Council (NRO EC) had announced that the Number Council (NC) concluded its work to review and update Internet Coordination Policy-2 (ICP-2): Criteria for Establishment of New Regional Internet Registries following its delivery of the ‘ASO AC Recommended Draft RIR Governance Document‘. The NRO NC is now sharing that document, including a redline version for comparison to the second draft, and a rationale document that details the changes between version two and version three of the document. ASO AC Recommended Draft RIR Governance Document: https://www.nro.net/policy/internet-coordination-policy-2/rir-governance-do… Redline version: https://www.nro.net/wp-content/uploads/RIR-Gov-Doc.-v3.-redline.pdf Rationale document: https://www.nro.net/wp-content/uploads/Draft-v3-Changes-and-Rationale-24082… The key changes in version three include: - Clearer definitions and decision-making provisions, including new or amended definitions for Audit, Compliance Review, Rehabilitation Plan, Temporary Emergency Continuity Arrangement, Temporary Emergency Operator, and Transition Plan. - A restructured Recognition process, with more detailed proposal and review requirements, a two-thirds Regional Internet Registry (RIR) support threshold, conflict-of-interest disclosure, clearer ICANN responsibilities, and greater transparency through the publication of assessments and rationales. - Clarifications to Service Region, Coordination Limitation, and Community Consultation provisions to improve readability and explain how consultation may occur during Recognition or Derecognition processes. - A revised audit and compliance framework, including a five-year regular audit cycle, a distinct Compliance Review process with safeguards against misuse, and clearer outcomes and follow-up through Rehabilitation Plans where needed. - Updated emergency continuity provisions, including terminology changes, the ability for an affected RIR to initiate a Temporary Emergency Continuity Arrangement for its own services, a lowered initiation threshold involving ICANN and two-thirds of the RIRs, a retained 90-day limit, and additional transparency safeguards. - A more detailed Derecognition process that emphasizes rehabilitation as the preferred path, aligns key steps with the Recognition process, clarifies ICANN’s review and decision-making role, requires publication of decisions and supporting documents, and applies a two-thirds RIR support threshold excluding the subject RIR. - New amendment safeguards that prevent the document from being amended during a Temporary Emergency Continuity Arrangement or while a proposal for Derecognition is pending. By setting out these changes and the accompanying reasons, the NRO NC hopes to help readers understand the major considerations weighed in developing version three and how the draft seeks to address the main community concerns during the feedback process. We sincerely thank everyone who has shared their insights, and we appreciate the time, thought and effort put in by our respondents. On behalf of the NRO NC * The NRO NC is also known as the Address Supporting Organization Address Council (ASO AC) within ICANN, where it serves as the body responsible for overseeing global policy development related to Internet number resources. -- Kind regards, Ulka Athale Community Development Manager RIPE NCC www.ripe.net

research survey on Segment Routing (SR-MPLS) traffic engineering practices
by Dekinder Florian 19 Aug '26

19 Aug '26

Dear colleagues, I am conducting a research survey on Segment Routing (SR-MPLS) traffic engineering practices in operational networks, as part of an ongoing measurement study at the University of Liège (Belgium). Our work builds on AReST, a methodology we developed to detect and characterize SR-MPLS tunnels from external traceroute measurements (paper: https://orbi.uliege.be/bitstream/2268/337150/1/paper.pdf — code: https://gitlab.uliege.be/segment-routing) The goal of this survey is to complement our external measurements with first-hand operational insight from network engineers and architects. If you are involved in the design, deployment, or operation of SR-MPLS in your network, I would greatly appreciate your input. The survey takes approximately 5 minutes and all responses will be kept strictly anonymized in any publication. Thank you for your time — every response helps, even if your deployment is limited or in early stages. Best regards, Florian Dekinder Contact: florian.dekinder(a)uliege.be<mailto:florian.dekinder@uliege.be> Link: https://forms.gle/2zPxABc2ZwL4Uxmn9
