ICMP is a key protocol to exchange control and error messages over the Internet. Unfortunately it is frequent that some routers along a given path do not correctly process this protocol. This document provides a taxonomy of the problem in order to help an end user who suspects ICMP-related problems to better understand the situation, and possibly identify the faulty router(s).
