Dear all,
ICANN announced the publication of the root-scaling study commissioned to Interisle
The report itself can be found here:
http://www.icann.org/en/committees/dns-root/root-scaling-study-report-31aug09-en.pdf [PDF, 1,340K]   

Background:
 In February 2009, with Resolution 2009-02-03-04, the ICANN Board requested the Root Server System Advisory Committee (RSSAC), the Security and Stability Advisory Committee (SSAC), and the ICANN staff, including the IANA team, to study the potential issues regarding the addition of IDNs, IPv6 addresses, DNSSEC and substantial numbers of new TLDs to the root zone. The Terms of Reference for this study are at http://www.icann.org/en/committees/dns-root/root-scaling-study-tor-05may09-en.htm.
 
Interisle was selected to perform this study. In the course of their study, they recommended that a modeling effort be undertaken with the assistance of TNO. TNO produced a model and a companion report.

The steering group will be evaluating the report against the Terms of Reference and preparing recommendations for the Board and the public.

Kind regards,
Bart
