Fast flux hosting and DNS

Fast flux hosting is an evasion technique used by phishers, identity thieves and other e-criminals to frustrate incident response team and law enforcement agency efforts to track down and take down illegal web sites. The fast flux technique closely resembles a 3 card monte shell game , where a tosser lays three folded playing cards on a table and a victim is lured betting on his ability to "follow the red queen" (Brits call this scam "Find the Lady"). The tosser moves all three cards at blinding speed while simultaneously distracting the victim with conversation, clever quips, and sleights of hand. Fast flux, however, is a high stakes trick, and has become a worrisome and omnipresent attack technique. In fast flux hosting, the tosser rapidly changes web site *and* DNS name server addresses, so quickly that there is virtually no time for investigators to respond.
