Title : Considerations on the IPv6 Host density Metric
Author(s) : G. Huston
Filename : draft-huston-hd-metric-01.txt
Pages : 18
Date : 2005-8-31
This memo provides an analysis of the Host Density metric as
currently used to guide registry allocations of IPv6 unicast
address
blocks. This document contrasts the address efficiency as
currently
adopted in the allocation of IPv4 network addresses and that
used by
the IPv6 protocol. It is noted that for large allocations
there are
very significant variations in the target efficiency metric
between
the two approaches.

A couple of observations.
I note from RFC3194 that it says "The examples suggest an HD-ratio
value
on the order of 85% and above correspond to a high pain level, at
which
operators are ready to make drastic decisions" and that "...this
suggests
that values of 80% or less corresponds to comfortable trade-offs
between
pain and efficiency."
So the argument here is that very large networks don't share the same
HD ratio property? I think it would be nice to state the crux of
the 'case'
of this draft in the intro section.
I guess the references for 3513 and 3177 should point to the -bis
versions
currently in draft?
draft-ietf-ipv6-addr-arch-v4-04
draft-narten-ipv6-3177bis-48boundary-00
This draft states assumptions about /48's, so should probably
discuss the
impact of /56's being the default? Or do you think Thomas' draft
should
discuss this? The two seem quite linked :)
