Problems arise when two nodes on the same link are (mis)configured
with the same IP address. This document describes (i) a simple
precaution that a host can take in advance of configuring and

(ii) a simple mechanism by which a host can passively detect
after-the-fact misconfigurations, so that the host may respond to
rectify the problem.
