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.庞夫人也跟着起身，这茶还热乎着呢。　　1840年，一个风雨交加的夜晚，泉州知府萧玉堂夫妇中年得子，不料生下一个肉团。萧夫人惊骇而亡，萧玉堂悲愤交加，命仆人将这一肉团丢弃。一药翁飘然而至剖开胞衣，一声惊天动地的啼哭，虚云就这样来到了人间，由此开始了他长达一百二十年，经历四十八奇的求道旅程。新世纪的钟声已经敲响，蓦然回首，我们发现在硝烟弥漫的商战中，人类的良知与正义是那样的可歌可泣。
