As part ICANN's ongoing efforts to ensure the stability of the DNS, ICANN staff contracted with the DNS Operations, Analysis and Research Center ( https://www.dns-oarc.net/) as independent and well-respected experts to provide an analysis of the impact of adding IPv6, DNSSEC, and additional top-level domains to the ICANN-operated L root server.
This study, while independent of the Root Server System Root Scaling Study (http://www.icann.org/en/announcements/announcement-29may09-en.htm) and focused specifically on the impact to the ICANN-operated L root server, has been used as input in the more comprehensive study undertaken by the Root Scaling Study Group.
The final report of the DNS-OARC study has now been published at http://www.icann.org/en/topics/ssr/root-zone-augementation-analysis-17sep09-en.pdf [PDF, 2,190K].
