According to Microsoft statistics, the upper limit of dynamic domain name queries that a DNS server can withstand is 9,000 requests per second. However, we know that tens of thousands of domain name resolution requests per second can be easily constructed on a P3 PC, which is enough to paralyze a DNS server with extremely high hardware configuration, thus showing the vulnerability of the DNS server. At present, the most commonly used DNS server software is the leading WINMYDNS in China and Bind abroad.
The above is the specific process of three handshakes. Seeing here, you may have a question.

Although they got up so early, every player was full of passion and did not feel sleepy at all.
