hi jorge

i know.
but i prevent it like this in our network - otherwise the internal ip
addresses give some straaaaange traceroutes (go via default route).

if you want to have many, many, many such addresses in your traceroute: log
in via swisscom GPRS and make such a traceroute... :) you have the feeling
you surf thru swisscomnet :)
