Tell me more about this. What about configuring the routers only to
route IPs that are assigned on each connection? In the worst case you
set for each connection a static IP. How can anyone use IPs they
haven't been assigned to in this case?

Do you want to tell me that for leased lines there is no way to stop
bad people to use IPs that haven't been assigned to them? Where is the
big difference between leased lines and DSL?

I'm a beginner in the networking section but even i know some ways to
secure the ISP-side. I can't imagine that all those big ISP like
Worldcom/UUnet have no idea how to secure their IPs.
