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.
