New gTLDs: Root Zone Scaling Report

27 June 2012

Report: Impact on Root Server Operations and Provisioning Due to New gTLDs [PDF, 4.75 MB]

ICANN is publishing the report "Impact on Root Server Operations and Provisioning due to New gTLDs." The report is a result of a request by ICANN's Governmental Advisory Committee to provide "a complete report with full analysis, including all underlying data of root zone scalability."

The report builds on past work but also includes additional areas of analysis to support this report's conclusion that the root zone can be grown in a stable manner. The new analyses include an additional, improved statistical model for projecting root zone growth, and an analysis of the impact of delaying root zone updates. These analyses and other important supporting information are included in the appendices.

The report is the result of close collaboration among technical ICANN Board, community and staff members. There were multiple iterations in order to arrive at a version that is responsive to the GAC request. Even with that, the report is published as a first version so that it can be amended in response to governments' or others' questions and requests for clarifications.

New reports are generally not published during ICANN meetings. This report, recently forwarded to the GAC, is being posted in response to other requests.
