Folks are sounding as if they'd never 'traceroute'd THROUGH a set of
unroutable IP addresses. I have seen cases where my 'traceroute' looked
like this [when I've had the patience to not hit Interrupt at the first
sign of stars]:
1 1 ms 1 ms 1 ms router.here
2 10 ms 10 ms 10 ms router.there
3 * * *
4 * * *
5 * * *
6 * * *
7 80 ms 80 ms 80 ms router.over.yonder
8 90 ms 90 ms 90 ms host.over.yonder
It works!
