DNS Server's IP address as his local IP address and thus breaking
DNS for everybody.

This wiki page has been inspired by my own experience as network admin, and legends and stories that I have been told numerous times in the past, most of them by people like Hanno Wagner, Jörg Hoh and Markus Wirtz.
