a.k.a. traceroute eXtreme
network topology mapping for the linux console.
how:
The program uses an algorithm - the "wu" algorithm - to guess routing tables.
Basically its like a traceroute but recursive on the network. So it gives you a tree view of the network, depending on how accurate the heuristics are.
There are different options that very clever people can use for different purposes.
You could use it to verify that everything works as expected on your net. You could possibly use it to check inter-AS routing (it does whois lookups) if you know what that is.
It is also possible with this program to verify the routing of a single router by
probing every address on the network at a certain 'hop'.
