When a server's IPv4 path and protocol are working, but the server's
IPv6 path and protocol are not working, a dual-stack client
application experiences significant connection delay compared to an
IPv4-only client.  This is undesirable because it causes the dual-
stack client to have a worse user experience.  This document
specifies requirements for algorithms that reduce this user-visible
delay and provides an algorithm.  [STANDARDS-TRACK]
