ICMP is a fundamental part of the Internet as it handles the control and error messages. ICMP's treatment by the network and in particular by different routers it may cross is therefore a key aspect driving troubleshooting and diagnosis processes. In this paper we present IBTrack, a tool that aims at characterizing how the network actually treats different ICMP messages from an user point of view. Specifically, we detail a classification algorithm to categorize router behaviors and we introduce
more » ... its associated refining method which exploits multiple probing protocols. We illustrate the average Internet router behavior and path composition through results gathered from Planet-Lab nodes using a large CAIDA's snapshot of routed /24. We further show that our refining method improves the routers behavior characterization up to 10% for more than 1% of the total number of observed routers.
