Technical Summary
 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.
