Domain Name System (DNS) is a basic and important services on the Internet. However, Distributed Denial of Service (DDoS) has been a threat to the security and stability of DNS for a long time. In this paper, we take a review of DDoS attacks based on DNS aiming to make a better understanding of it. Firstly, we analyse the security vulnerabilities of DNS related to denial-of-service attack. Then we discuss the classification of DNS DDoS attacks, and divide them into four categories according to the attack mode. Finally, we summarize the existing defense methods of two aspects. We aim to get a better understanding of the DDoS attacks based on DNS and expand the understanding of DDoS attacks.
