IANA RC Reports

The IANA Numbering Services Review Committee (IANA RC) publishes the IANA Performance Matrix Summary Report during the first quarter of each year. The report pertains to the numbering services that IANA provided to the Numbers community during the previous year.

When the IANA Performance Matrix Summary Report is published, a 30-day comment period begins and the five RIR communities are invited to provide input.

At the end of the comment period, the IANA RC reviews and summarizes any input received and compiles its final report.

Comments received from the community during the comment period are publicly archived on this website and can be viewed by following the ‘Comments Received’ links in the table below.
