Talking about which, it often amazes me to see how often the script is run with targets of 192.168.x.y and 10.x.y.z. There are plenty of less-clueful people out there.
OTOH it's often amusing to see how many hops a 'non-routable' packet can travel from various places before it gets dropped.
There's nothing "un-routable" about a packet with an RFC1918 source or destination address. The distinction between RFC1918 and non-RFC1918 addresses is simply one of scope (if they were "un-routable" they wouldn't be very useful for private use). (which is not to say that ISPs shouldn't drop such packets, out-of-scope, at their customer edges using RPF or some other sensible strategy) Joe
