Answer 1

Been reading worm books? A "Dark IP" generally has no use to you and I. It can be used to monitor a large system or create a backdoor to a system. It is not a common use term except to hackers or crackers or system administrators who monitor the entire system traffic stream..
Dark IP address is space that is globally routable, but currently there are no computers in this network.

Here is one article that "mentions" the concept

http://www.ilan.net.il/research/telescope/
ok one more source for utilization (legally)
http://www.cymru.com/Darknet/

All I can say is it generally is not used for anything LEGAL except to "suck" in those who are attempting to attack a network.
