In renumbering scenarios where an IPv6 prefix suddenly becomes invalid, hosts on the local network will continue using stale prefixes for an unacceptably long period of time, thus resulting in connectivity problems. This document specifies an algorithm that allows host implementations to infer when configuraton information has changed, such that they can phase stale information out in a timelier manner.
