Google/Youtube assistance
by Dennis Burgess - LTI Support 05 Nov '25

05 Nov '25

We have had a network that directly peers with Google, traffic goes though the peering without issues, no latency issues. However, we have periods of not being able to reach youtube.com and customers are having issues getting playback though YouTube. Starting around 5pm PST.. It’s a on/off issue, but looking for someone at YouTube/google to take a few playback ids and see what they can see. See if we can figure it out. So looking for google/YouTube person to email me off list to discuss.

CAIDA and Internet2 are working on a tool to assist network operators plan their RPKI-ROAs
by Steven Wallace 01 Nov '25

01 Nov '25

You can kick the tires here: https://rootbeer.testing.ns.internet2.edu/roa-planner/ The implementation remains fragile and will be unavailable intermittently, but we hope to improve it over the next couple of weeks. Please send me (ssw(a)internet2.edu) any suggestions, concerns, etc. From the help page: The RPKI-ROA Planner is a tool designed to help network operators efficiently plan their Route Origin Authorizations (ROAs), which are vital for securing BGP routing. To generate a comprehensive set of ROA recommendations for a user-supplied IP prefix, the Planner aggregates routing and registration information from four key sources: - Internet Routing Registry (IRR): Route Objects are gathered from services like https://stat.ripe.net/data/whois/. - Regional Internet Registries (RIRs): IP registration data is fetched from sources such as https://rdap.arin.net/registry/ip/. - Routing History: Historical routing data is analyzed using services like RIPEstat (https://stat.ripe.net/data/routing-history) - Global Route Views: The Planner includes routes observed in the global research and education community (via Routeviews). Crucially, these routes may be longer (more specific) than those typically seen in the Default-Free Zone (DFZ). Assumption: If a route was observed in the past, is currently visible, or is documented in an IRR object, it is a candidate for a new ROA. It excludes any candidate routes that are already covered by an existing, valid ROA, ensuring you only focus on what's missing. All candidate routes are presented to you in the table. You have full control to deselect individual routes or use age filters to exclude older, potentially stale data before the final ROA set is calculated. The Planner prioritizes generating multi-prefix ROAs (covering multiple routes with one authorization) over single-prefix ROAs. Using multi-prefix ROAs is the recommended best practice for maintaining cleaner, more efficient RPKI records. thanks! Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu

by Sofia Silva Berenguer 30 Oct '25

30 Oct '25

(Apologies for duplication) Hello all, The NRO RPKI Program [1] has published a blog post explaining the proposed solution to concerns with the current RPKI Trust Anchor configuration, now documented in the Internet-Draft https://www.ietf.org/archive/id/draft-nro-sidrops-ta-constraints-00.txt The draft defines a mechanism that allows RPKI Trust Anchors (TAs) to declare which TA is authoritative for which Internet Number Resources, helping prevent RPKI validation conflicts. You can read the blog post here: https://www.arin.net/blog/2025/10/29/nro-rpki-program-series-6/ We welcome feedback and discussion on the sidrops mailing list [2] and during the upcoming SIDROPS WG session at IETF 124 (Montreal, Nov 3) [3].

IPinfo Geolocation Advice Needed
by Mark Blackford 24 Oct '25

24 Oct '25

Greetings, Does anyone have any suggestions on how to get IPinfo to properly report Geolocation for NNI pint to point type circuits? I have a geofeed that they are ignoring, but I have two prevailing theories. One - someone put our entire ARIN aggregate in it last month and now it overlaps everything in the feed. I read that overlapping prefixes cause confusion. I took it out of the feed today, but IPinfo is so secretive I have no idea if they will remove it. Two, and the more likely theory based on their boast on how they beat the competitor by thousands of miles, is they are reporting on the wrong end based on their ping scans. They ping the hub end of a /31 and disregard the other end that is usually two to three states away. Therefore , they are the ones horrible off an their competitors are spot on. Should I not be reporting the point to point /31 and only use he customer /32 end? Any other advice in properly identifying the location for Ipinfo would be awesome. All the other providers seem to properly follow my geofeed, and I have no issues with them. Thank you very much, Mark Blackford

mitigations for the BGP vortex attack

Hi. I recently read an interesting research paper that I don’t think has been shared here yet: https://www.usenix.org/system/files/usenixsecurity25-stoeger.pdf I would throw out two additional thoughts related to "Partial Mitigations"(6.1): 1. Usage of modern, multi-threaded routing daemons which are able to take advantage of multi-core control plane CPUs. 2. Control plane CPU usage monitoring. BGP per-neighbor sent and received UPDATE messages rate monitoring. For example, Junos supports this via SNMP, telemetry or RPC. In the "Safe BGP Communities"(6.2) paragraph the paper advises networks to cease the support of "Lower Local Pref Below Peer" community. As the BGP vortex forms only when both the "Lower Local Pref Below Peer" and "Selective NOPEER" communities are present, then perhaps alternative approach would be to cease the support of those two communities together. In other words, both communities would still be allowed separately, but not together. I did a brief analysis on RIPE RIS data for NTT, GTT and Sparkle "Lower Local Pref Below Peer" and "Selective NOPEER" type communities and the combination where both types are attached to the prefix are rare. Finally, I wonder if or how much the attack is amplified if the adversary ensures(for example, using communities) that each announced prefix has unique path attributes and thus there is an UPDATE message per prefix.
