The threats and consequence presented by denial of service attacks have resulted in the proliferation of research ideas, studies and commercial products intended to mitigate their negative impact through technological approaches. Packet fl ooding denial of service attacks have specifi cally garnered both widespread attention and signifi cant investment. It is therefore surprising that few studies have been published detailing specific attacks and how operators have responded to them. In this paper we attempt to provide insight into some of the packet fl ooding distributed denial of service attacks that we as operators have experienced. We focus specifi cally on attacks against a domain name system service provider since that is our area of expertise. We elucidate the nature of the attacks, how they are often mitigated in practice and attempt to explain what the true motives behind these attacks have been.
