As introduced in [RFC5887], renumbering, especially for medium to large sites and networks, is currently viewed as expensive and painful. This error-prone process is avoided by network managers as much as possible. If IPv6 site renumbering continues to be considered difficult, network managers will turn to Provider Independent (PI) addressing for IPv6 as an attempt to minimize the need for future renumbering. However, widespread use of PI addressing may create very serious BGP4 scaling problems [RFC4984]. It is thus desirable to develop tools and practices that make renumbering a simpler process and reduces demand for IPv6 PI space.

                    IPv6 Site Renumbering Gap Analysis


   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.
