Over the last couple of weeks, what started out as a simple perl script to map the IP's of the fast flux domain ibank-halifax.com has since turned into a complete system, with a database backend for tracking changes to FF domains.
Shortly, I hope to soon release the implementation so that other people can learn from and build on what I've done.
