 -m maxhop   the maximum number of hops a target which is dumped may be away.

Passivly sniffs the network and dump all client's IPv6 addresses detected.
Note that in a switched environment you get better results when additionally
starting parasite6, however this will impact the network.
If a script name is specified after the interface, it is called with the
detected ipv6 address as first and the interface as second option.
