As a result of the successful IANA Stewardship Transition in 2016, the IANA Numbering Services are managed through a Service Level Agreement between ICANN and the five Regional Internet Registries (RIRs).
In the same year, the IANA Numbering Services Review Committee (IANA RC) was established. The IANA RC is composed of representatives from each RIR region and advises and assists the RIRs in the review and evaluation of the IANA Numbering Services.
The operational delivery of the IANA Numbering Services is currently performed by Public Technical Identifiers (PTI). PTI publishes detailed monthly performance reports, which are available on the IANA Numbering Services website.
Based on these monthly reports, the five RIRs have compiled the 2025 IANA Performance Matrix Summary Report.
30-Day Public Comment Period
The IANA RC is now opening a 30-day public comment period to seek input from the global Internet number community regarding the performance of the IANA Numbering Services and the findings contained in the 2025 IANA Performance Matrix Summary Report.
All members of the Internet number community are encouraged to review the report and provide feedback.
Comments on IANA service performance should be submitted to: iana-performance [at] nro [dot] net
The IANA RC will publish its annual report in March 2026 as formal advice to the NRO Executive Council. This report will be based on the Performance Matrix Summary Report and on the input received from the community during this consultation process.
The public comment period will close on Friday, 6 March 2026 at 23:59 UTC.
All comments received will be published on the NRO website in the dedicated IANA RC section and will be carefully considered as part of the preparation of the final report. Following the conclusion of the comment period, the IANA RC will meet to review and evaluate all submitted feedback.
