Abstract:
   This draft proposes the use of arbitrary length prefixes in PIO for
   SLAAC.  A prefix of length 63 in PIO, for example, would be permitted
   to form an address whose interface identifier length is 65, which
   allows several benefits.  A prefix of length 65 would be allowed too,
   but it SHOULD NOT be used on a large scale, like at a large ISP; this
   is to avoid a race to the bottom.

   The implementation uses a parameter in the Host; this option is off
   by default.  In that case, the Host respects the 64bit boundary.
   When the parameter is set to on the Host accepts prefixes of lengths
   different than 64 and forms 128bit addresses.

   In the past, various IPv6 addressing models have been proposed based
   on a subnet hierarchy embedding a 64-bit prefix.  The last remnant of
   IPv6 classful addressing is a inflexible interface identifier
   boundary at /64.  This document proposes flexibility to the fixed
   position of that boundary for interface addressing.
