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://www.ietf.org/archive/id/draft-bensley-rpsl-exclude-members-00.html
With kind regards,
James.

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)

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>

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:

We are looking forward to welcoming you in the webinar.
Kind regards,
Wout de Natris - van der Borght

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>

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:

We are looking forward to welcoming you in the webinar.
Kind regards,
