Resolve DNS errors that prevent browsing failures

When IE can't browse the webpage, you can try to use IP address to access first. If it can be accessed, it should be a DNS problem. The DNS problem may be caused by DNS error or DNS server itself when connecting to the network. You can manually specify the DNS service.

This address can be the DNS server address provided by your local ISP, or you can use the DNS server address elsewhere. In the properties of the network, the Control Panel - Network and Dial-up Connection - Local Connection - Right-Click Properties - TCP /IP Protocol - Properties - use the local DNS server address. Different ISPs have different DNS addresses. Sometimes it is a router or network card problem, and can't connect with the ISP's DNS service. In this case, you can turn the router off for a while or reset the router.
In order to improve the speed of website access, the system will automatically save the website that has accessed and obtained the IP address into the local DNS cache. Once the website is accessed again, it will not be directly cached from the local DNS through the DNS server. Remove the IP address of the website for access. Therefore, if there is a problem with the local DNS cache, the website will be inaccessible. You can rebuild the local DNS cache by executing ipconfig /flushdns in Run. (Note: there is a space after ipconfig).
