Some Thought on the Paper: Practical Challenge-Response for DNS

Because the speed of DNS is so important to the performance of any connection on the 'net, a lot of thought goes into making DNS servers fast, including optimized software that can respond to queries in milliseconds, and connecting DNS servers to the 'net through high bandwidth links. To set the stage for massive DDoS attacks based in the DNS system, add a third point: DNS responses tend to be much larger than DNS queries. more
