[dns-operations] Upcoming Registry Service Provider Evaluation Program

Thu Feb 22 18:01:22 UTC 2024

I have some data on this.  Trying to convey this in email is hard, so here’s a link to slides from Nov 2022 explaining the data:

https://www.icann.org/en/system/files/files/presentation-consolidation-amongst-top-level-domains-15nov22-en.pdf

Below is a chart (pulled from debug output) for 18 Feb 2024 (a few days ago), if you want more current observations.

This supports the notion that most gTLDs are hosted on some large platforms, ccTLDs generally are separate.  There are some crossovers, of course.  Revmap refers to the RIR managed top-level IPv4 and IPv6 zones.  I think there is only one platform serving all three, thanks to Japan’s NIR function.

Note - you may see separate organizations in one line.  This is an artefact of how the groupings are made.  While zones are transferring, it might make it look like two organizations have merged, which is not the case.  It’s more a matter of transitioning the DNS zone management (SOA resource record) and updating the root zone database.  Once transfers finalize, this data will separate the two organizations again.

I did some of the technical evaluations in the previous round, and we
saw that the vast majority of applications used about five back end
providers. Prequalifying those providers would have made the whole
process much faster.
