                   IPv6 Site Renumbering Gap Analysis

Abstract

   This document briefly introduces the existing mechanisms that could
   be utilized for IPv6 site renumbering and tries to cover most of the
   explicit issues and requirements associated with IPv6 renumbering.
   The content is mainly a gap analysis that provides a basis for future
   works to identify and develop solutions or to stimulate such
   development as appropriate.  The gap analysis is organized by the
   main steps of a renumbering process.
