My company supports this proposal moving forward. On the one hand
as a large network operator we have the need to deploy hierarchy
in our IPv4 networks and thus the HD ratio is a fairer way of
measuring addresses used, i.e. locked up by the network architecture.
While it is possible to mitigate this by carrying lots of small
prefixes internally, this creates unacceptable scaling issues of
its own. The HD ratio policy, submitted by Alain Bidron, strikes
a balance between these issues.

Of course, some have noted that this will cause a small reduction
in the overall lifetime of IPv4 addresses and feel that this will
penalize emerging regions. We do not believe this is so, since there
are still many years left for emerging regions to acquire IPv4 addresses
and build infrastructure. At the same time, IPv6 has matured as
a technology and presents the emerging regions with an opportunity
to leapfrog over developed countries. By doing this they will have
no dependency on IPv4 addresses nor will they need to deal with the
complexities that have been grafted onto IPv4 over the years. I note
that in Asia, the takeup of IPv6 has been quite a bit stronger than
in most of the developed world. My company, and many of the companies
supporting this proposal, operate IPv6 networks as well.

I agree and I strongly urge Alain to go back to the members of
ETNO who drafted Expert Contribution 064
http://www.etno.be/Portals/34/ETNO%20Documents/Information%20Society%20i2010/EC064%20-%20NANI%20EC%20on%20IPv4%20AD%20ratio.pdf
and get them to come to this mailing list and explain the reasons
behind their support of this policy proposal.
