2. Detects destination unreachable and reports reason

When doing a traceroute to a remote host, it is possible an intermediate router will respond that the destination is unreachable and give a reason code. IPNetMonitor listens for this response, stops waiting for the trace response, and reports the reason code.

A red "X" indicates no response within the timeout period. An orange "X" indicates an ICMP destination unreachable response was received.

AGNetTools acts as if the trace completed successfully.

Mac TCP Watcher correctly indicates the host is unreachable (!Host) and stops.

OTTool correctly reports the host is unreachable.

WhatRoute correctly indicates the host is unreachable (!H), but doesn't stop tracing.
