Details of the analysis are available on our web site at: http://www.ripe.net/ripe/policies/proposals/comments/impact_of_hd.html

I think you gave out the wrong URL. All I can find at that address is a brief summary. Where is the detailed analysis?

The goal of the analysis was to estimate the overall effects of the proposed policy. As such we do not single out specific registries, but only publish what the total number of additionally allocated addresses is projected to be if policy 2005-01 had been adopted 3 years ago. The URL above lists those numbers and shows how the number of allocated addresses would have developed over time. The second half of the page describes how we arrived at those numbers, i.e. the model used and the assumptions behind it. As with all models dealing with IP consumption rates, there are uncertainties and there is no guarantee history would have unfolded as projected by the model. However, larger networks operators have stated that applying an HD-ratio is useful to them as it will help them add hierarchy to their networks. Since applying an HD-ratio will mean those networks are eligible for more address space and need to use less of an allocation before applying for a next one, address space consumption is likely to increase. The remaining pool of unallocated IPv4 addresses will thus last shorter. -- Rene =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rene Wilhelm RIPE Network Coordination Centre Email: wilhelm@ripe.net Amsterdam, the Netherlands Phone: +31 20 535 4417 Fax: +31 20 535 4445 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
