Generally, the abstract parent class encapsulates the algorithm framework of the subclass, including implementing some common methods and encapsulating the execution sequence of all methods in the subclass. The subclass can inherit the parent class and rewrite the methods of the parent class in the subclass, thus realizing its own business logic.The attack uses the method of sending a large number of domain name resolution requests to the attacked server, Usually the domain name requested to be resolved is randomly generated or does not exist on the network. When the attacked DNS server receives the domain name resolution request, it will first look for whether there is a corresponding cache on the server. If it cannot be found and the domain name cannot be directly resolved by the server, the DNS server will recursively query the domain name information from its upper DNS server. The process of domain name resolution brings a great load to the server. If the number of domain name resolution requests exceeds a certain number per second, the DNS server will time out to resolve domain names.1.
