Abstract 

   This document analyzes enterprise renumbering events and describes 
   the best current practice among the existing renumbering mechanisms. 
   According to the different stages of renumbering events, 
   considerations and best current practices are described in three 
   categories: during network design, for preparation of renumbering, 
   and during a renumbering operation.

1. Introduction 

   IPv6 site renumbering is considered difficult. Network managers might 
   prefer to use Provider Independent (PI) addressing for IPv6 to 
   attempt to minimize the need for future renumbering. However, 
   widespread use of PI may create very serious BGP4 scaling problems  
   and PI space is not always available for enterprises according to the 
   RIR (Regional Internet Registry) policies. It is thus desirable to 
   develop mechanisms and practice guidelines that could make 
   renumbering a simpler process to reduce demand for IPv6 PI spaces.  

   This document undertakes scenario descriptions, including 
   documentation of current capabilities and existing BCPs, for 
   enterprise networks. It takes [RFC5887] and other relevant documents
