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.

Some families have seen the phenomenon of "poverty due to illness and returning to poverty due to illness". The implementation of the national new rural cooperative medical system has effectively relieved the economic pressure of patients' families. To a certain extent, it has curbed the phenomenon of returning to poverty due to illness and causing poverty due to illness, promoted the development of rural health services, promoted the change of farmers' concept of seeking medical treatment, and also enhanced the image of the Party and the government for private affairs. However, many farmers still do not know enough about this policy.
