draft-romijn-grow-rpsl-registry-scoped-members
by James Bensley 31 Mar '26

31 Mar '26

Hi all, There were some discussions at RIPE91 about supporting the following draft. There is now a WG call to adopt the draft, so responses on the GROW mailing list to get the draft adopted would be greatly appreciated: https://mailarchive.ietf.org/arch/browse/grow/?q=draft-romijn-grow-rpsl-reg… For those that don't know the draft, it can be found on the IETF datatacker: https://datatracker.ietf.org/doc/draft-romijn-grow-rpsl-registry-scoped-mem… This draft addresses the ambiguity of references between sets in RPSL, where currently one set includes another by its RPSL primary key. As the same primary key may exist in multiple IRR registries, these references are ambiguous, while the referred objects sometimes have very different contents. The draft adds a new attribute where references to other sets must be scoped to a specific IRR registry. Specific resolving and validation rules ensure that we keep backwards compatibility with older RPSL objects, authoritative servers, and resolvers. At the same time, it provides benefits even with partial deployment With kind regards, James Bensley (he/him) [CompanySignature] Inter..link GmbH | Boxhagener Straße 80, 10245 Berlin, Germany | Managing Directors: Marc Korthaus, Theo Voss | Commercial Register: Amtsgericht Charlottenburg, HRB 138876 | VAT ID: DE281288887 | Email: hello(a)inter.link<mailto:hello@inter.link> | Web: inter.link<https://inter.link>

Hi, I thought this might be interesting for this list. Wout de Natris asked me to forward it. Kind regards, Mirjam -------- Forwarded Message -------- Subject: [cooperation-wg] Invitation to Post-Quantum webinar on routing and RPKI Date: Fri, 20 Mar 2026 14:00:20 +0000 From: Wout de Natris - van der Borght <denatrisconsult(a)hotmail.nl> Reply-To: Wout de Natris - van der Borght <denatrisconsult(a)hotmail.nl> To: cooperation-wg(a)ripe.net <cooperation-wg(a)ripe.net> Dear colleagues, Imagine a quantum or hybrid computer strong enough to break the algorithms that make up the core of the internet. Routing and RPKI are one example. What are the implications for us users, your organisation and society as a whole and what is the solution to prevent this from happening? On Thursday 2 April, 12.00 - 13.15 UTC, IGF DC-IS3C and Afnic organise its third and final PQC webinar that focuses on the need for a timely and coordinated PQC transition that will secure the routing layer of the internet. You can register with the IGF secretariat to participate here: https://intgovforum.zoom.us/webinar/register/WN_Hp1HQB8TRXebF-2Xuj3H2A <https://intgovforum.zoom.us/webinar/register/WN_Hp1HQB8TRXebF-2Xuj3H2A> We are looking forward to welcoming you in the webinar.

Fwd: Invitation to Post-Quantum webinar on routing and RPKI
by Mirjam Kuehne 20 Mar '26

20 Mar '26

Hi, I thought this might be interesting for this list. Wout de Natris asked me to forward it. Kind regards, Mirjam -------- Forwarded Message -------- Subject: [cooperation-wg] Invitation to Post-Quantum webinar on routing and RPKI Date: Fri, 20 Mar 2026 14:00:20 +0000 From: Wout de Natris - van der Borght <denatrisconsult(a)hotmail.nl> Reply-To: Wout de Natris - van der Borght <denatrisconsult(a)hotmail.nl> To: cooperation-wg(a)ripe.net <cooperation-wg(a)ripe.net> Dear colleagues, Imagine a quantum or hybrid computer strong enough to break the algorithms that make up the core of the internet. Routing and RPKI are one example. What are the implications for us users, your organisation and society as a whole and what is the solution to prevent this from happening? On Thursday 2 April, 12.00 - 13.15 UTC, IGF DC-IS3C and Afnic organise its third and final PQC webinar that focuses on the need for a timely and coordinated PQC transition that will secure the routing layer of the internet. You can register with the IGF secretariat to participate here: https://intgovforum.zoom.us/webinar/register/WN_Hp1HQB8TRXebF-2Xuj3H2A <https://intgovforum.zoom.us/webinar/register/WN_Hp1HQB8TRXebF-2Xuj3H2A> We are looking forward to welcoming you in the webinar.

Information for ASPA creation
by Koen van Hove 06 Mar '26

06 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.
