AntiRoute prevents and logs UDP-based route tracking.
Programs like traceroute utilize the IP protocol's TTL (`time to live') field to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to a host, or an ICMP PORT_UNREACH from the host itself.
This is of course impossible if the target ports are open. AntiRoute listens on ports used in UDP-based route tracking and determines the IP address, source port and distance (in hops) of the host from which the trace is being performed.
