This memo provides an analysis of the Host Density metric as it is
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.  Note that for large allocations there are
very significant variations in the target efficiency metric between
the two approaches.  This memo provides information for the Internet 
community.
