Technical Summary
This document discusses problems that can occur when dual stack nodes
that have IPv6 enabled by default are deployed in IPv4 or mixed IPv4
and IPv6 environments. The problems include application connection
delays, poor connectivity, and network insecurity. The purpose of
this memo is to raise awareness of these problems so that they can be
fixed or worked around, not to try to specify whether IPv6 should be
enabled by default or not.
