Information for ASPA creation
by Koen van Hove 02 Mar '26

02 Mar '26

Hello all! I am currently working on a better ASPA UI in Krill. The goal is to provide a bit more confidence when creating an ASPA record that what was entered is correct, and, more importantly, does not accidentally break things once networks start validating and rejecting routes based on ASPA records. The last iteration of that UI can be found here: https://github.com/NLnetLabs/krill-ui/pull/58 I know this topic was also discussed during the last Routing WG in Romania (https://ripe91.ripe.net/programme/meeting-plan/sessions/30/transcript/) and I know the RIPE NCC does not (currently) do this because there are a lot of asterisks. But I wanted to give it a shot anyway :-) Currently I do two things: 1. Show the likely AS name when you enter an AS number, to prevent simple typos (8283 instead of 8382, etc.); 2. Show which AS numbers appear "to the left" in RIS (without making a claim that they are missing per se, just that they were observed) along with their names. But as I am not an operator (apart from AS211321, which is a very small network), I wanted your input as well. What is the kind of information you would want (or not want) to see before clicking the "Create ASPA" button? Cordially, Koen van Hove PS: This does not affect the CLI and API for Krill at all, it's only the web interface.

SR-MPLS traffic engineering Survey
by Dekinder Florian 24 Feb '26

24 Feb '26

Hello community, I’m Ph. D. Student at University de Liège, Belgium, and I’m conducting a survey as part of my researches on Segment Routing (SR) traffic engineering practices among network operators. We have a technique, called ArEST, allowing us to discriminate SR-MPLS and regular MPLS traffic. See https://orbi.uliege.be/bitstream/2268/337150/1/paper.pdf and our Git https://gitlab.uliege.be/segment-routing. If you are involved in the management of SR in your network, I would greatly appreciate your input. The survey should take no more than 5 minutes to complete. Link to the survey<https://docs.google.com/forms/d/e/1FAIpQLSc0vz9hX5VF_Ii2bprgC1neZwVnaA5tGS3…> Best regards, Florian Dekinder Université de Liège

Need your advice for my BGP Tool
by bogdancyber 31 Jan '26

31 Jan '26

Hello! My name is Bogdan Mihai, I'm 21 yr old from Romania. I recently invented something a little more abstract for BGP security, and I'm almost sure that there is nothing similar. I wasn't inspired by anything when I created this, it was a purely random idea that came to my mind. I'm not even an expert in this field, but from the beginning I saw security from a different angle than the others. I made a tool that basically builds a map of risk areas globally, areas where if someone were to try a hijacking attack, that attack would be successful. This idea came to me when I realized that BGP security is still a big problem. RPKI adoption is still slow. And the problem is that today's security in BGP is more reactive, it comes into play only after the attack is detected and damage is done. So I leave you here the link to the zenodo site where I posted my invention. https://zenodo.org/records/18421580 What I ask of you, and extremely important, is not to analyze every file there, but at least the product overview to understand the idea and tell me who this would be useful to, which company or organization. I know that maybe not everything is perfect there, I'm no expert, but I want to know if this idea really has value. Someone said this (You will probably have the same question): "I have to admit that I haven't read all the files, but from the summary, my first question was "how can anyone benefit from this information?" You wouldn't block traffic from a particular AS just for its safety, just like you wouldn't stop driving just because there are bad drivers around. It seems to me that this could be a research topic to raise awareness of the problems and that's it." And I answered: "Correct — this system is not intended to directly block ASNs. It is a risk intelligence tool, showing where there is real potential for abuse and impact. Think of it as: - city crime maps - seismic risk maps - financial fraud maps No one is "blocking the city" or seismic zones, but everyone uses these maps for preventive decisions and prioritization. In the same way, our tool helps operators and security teams decide where to apply controls, strict ROV or additional monitoring, before an incident occurs." I'm very confused and sad because I worked on this but I don't know who it would be of value to or if it even has any value. I appreciate every opinion.
