14 March 2022

We Need Your Input!

The objectives of the Root Zone Update Process Study were to:

  • Investigate whether there is a need to increase the robustness of the operational arrangements for making changes to the root zone content, and if so, how.
  • Identify any single points of failure that may exist.
  • Offer recommendations on how to reduce or eliminate them, should they exist.

The study was focused on the processing of change requests to the Domain Name System (DNS) root zone. The study provider looked for opportunities to improve the overall architecture and process along several dimensions: efficiency, robustness, conformance to policies established by the ICANN community, and confidentiality.

ICANN org requests community review of the initial version of the study.

Root Zone Update Process Study


In April 2020, ICANN org announced a request for proposal to find a contractor to perform the Root Zone Update Process Study called for in the IANA transition proposal as described above. An international consortium led by JAS Global Advisors (ICJ) was selected, following ICANN org's standard procurement process. The team worked closely with ICANN org (the IANA Functions Operator staff) and in consultation with Verisign (the Root Zone Maintainer) staff to gather information required to perform the study. The team also surveyed many top-level domain (TLD) operators, as described in the study.

ICANN org is interested in the community's feedback on the study, hence this Public Comment.

Next Steps:

ICANN org and the study provider will prepare a final version of the study after reviewing community feedback from this Public Comment.

ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a nonprofit public benefit corporation with a community of participants from all over the world.
