   DHCPv6 Prefix Delegation [RFC3633] allows a requesting router to
   include a prefix-length hint value in the IA_PD option to indicate a
   preference for the size of the prefix to be delegated, but is unclear
   about how the requesting router and delegating router should act in
   different situations involving the prefix-length hint.  This document
   provides a summary of the existing problems with the prefix-length
   hint and guidance on what the requesting router and delegating router
   could do in different situations.
