DNS Fluxing

the use of a system called a Domain Generation Algorithm botnet to perform one of the following attacks:

  • Fast Fluxing: Forcing rapid swapping in and out of IP addresses, with extremely high frequency through changing DNS records with brief TTLs
  • Domain Fluxing: Forcing constant changing of and allocation of multiple fully-qualified domain names (FQDNs) to a single IP address on the recursive or authoritative DNS server.
