Dear Working Group Members, Please find below a newly submitted document: "Explicitly excluding objects from RPSL sets". The purpose of this document is to address the issue faced by many operators today; namely that AS-SETs and ROUTE-SETs contain member entries which are undesirable for one reason or another, but the set owner has no method to exclude these unwanted members from their own set because they are deep within the set hierarchy. I have spoken to several people in the community who suffer from this problem and would like something done about it. In the long term we hope to phase out IRR based filtering, but we are many years away from that, so in the mean time we’d like to improve the situation until such time. Feedback and support from the community is appreciated. https://datatracker.ietf.org/doc/draft-bensley-rpsl-exclude-members/ https://www.ietf.org/archive/id/draft-bensley-rpsl-exclude-members-00.html With kind regards, James.

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>

Fwd: Invitation to Post-Quantum webinar on routing and RPKI
by Mirjam Kuehne 23 Mar '26

23 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.

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.
