Why can't some web pages be opened?

Usually there is something wrong with the DNS resolution of the computer, and the web page can't be opened.

Clearing DNS resolution cache, the system will generally cache commonly used DNS addresses, which can speed up the rapid access to the network, but sometimes these DNS addresses are abnormal for some reason, which will lead to the failure to open the web page normally, thus leading to the failure to open the web page. Understanding DNS cache can generally solve the problem.

If the web page cannot be opened normally after clearing the system DNS resolution cache, it may be that the DNS resolution server used by the current system has failed. In general, the Internet automatically obtains the IP address and DNS server address through the router, so it is necessary to manually set the DNS resolution server address of the system.
