In the process of DNS resolution, the client initiates a query request, and the DNS server may need to make additional queries to complete the resolution process and give a response, which will consume certain computing and network resources. If an attacker uses a large number of controlled hosts to continuously send resolution requests for different domain names, the cache of the DNS server will be continuously refreshed, and the failure of a large number of resolution requests to hit the cache will cause the DNS server to consume additional resources for iterative queries, which will greatly increase the resource consumption of the DNS server.
