NRO RPKI Program — 2025 in Review

This blog post is part of the NRO RPKI Program series. Read the previous posts here.

2025 is coming to an end, and we want to pause to reflect on our achievements this year as part of the NRO RPKI Program.

A significant achievement was submitting the first draft specification to address concerns about RPKI Trust Anchors (TAs) claiming resources for which they are not authoritative (read more about this milestone). After presenting this draft to the SIDROPS IETF Working Group during the IETF 124 meeting, the RPKI Steering Group received input from the technical community and engaged with various stakeholders. The group is now discussing options for the next draft version. Look for updates in the new year and join the SIDROPS mailing list to participate in the discussions.

Additionally, we published a series of joint RPKI baseline documents. The first document outlines the process of creating ROAs through each Regional Internet Registry (RIR) portal and is covered in a previous blog article. The second document provides an overview of RPKI services and features currently offered by each RIR.

Following up on the core RPKI services and features shared in a previous blog article, we have now published a roadmap for these services to be offered by all RIRs. Notably, all RIRs are committed to supporting Autonomous System Provider Authorizations (ASPAs) by the end of 2026. RIPE NCC has released a new version of their RPKI system supporting ASPAs, and ARIN has activated ASPA functionality in their Operational Test and Evaluation Environment for testing. As part of the RPKI Program, RIRs will continue coordinating on ASPA support implementation.

Other useful documents published this year include the RPKI Content Repository and a summary of RPKI best practices and lessons learned.

From the NRO RPKI Program, we express our gratitude to all members of the Internet community who shared their thoughts, ideas, and feedback, either proactively or in response to requests. This input helps us ensure that the resources we produce and the work that we do are comprehensive and useful for all RPKI implementers.
