Abstract

This document describes a procedure that can be used to renumber a network from one prefix to another. It uses IPv6's intrinsic ability to assign multiple addresses to a network interface to provide continuity of network service through a "make-before-break" transition, as well as addresses naming and configuration management issues. It also uses other IPv6 features to minimize the effort and time required to complete the transition from the old prefix to the new prefix.
