  Denial-of-Service attacks continue to be a serious problem for the Internet
community despite the fact that a large number of defense approaches has been
proposed by the research community. In this paper we introduce IP Fast Hopping,
easily deployable and effective network-layer architecture against DDoS
attacks. Our approach also provides an easy way for clients to hide content and
destination server of theirs communication sessions. We describe a method of
dynamic server IP address change and all modules necessary to implement the
approach.
