However, the workload of maintaining these level two domain names is very high, but we can solve this problem by using a generic domain name resolution technique, so that support for the generic domain name can be achieved by slightly setting up a DNS server with its own Windows system. 　　 The following are examples of Windows Server 2003 and Windows 2000

Generally, the performance and timing problems of dns are caused by suspicious query results. In this case, no matter whether the dns is parsed or not, the consequences are the same. What should we do for actual problems such as long response time, timeout errors, and invalid cache? After all, these types of query responses are still possible to pass. It only requires more time. In fact, in this case, the w
