(The principle of smart DNS is very simple: when a user resolves a domain name, it determines the IP used by the user, and then matches it with the IP table inside the DNS server to see if the user is a telecom or China Netcom user, and then returns the corresponding IP address to the user. . The current domain name service operators do not provide smart DNS services, so they must set up their own DNS services or use free online smart DNS services, such as DNSPOD.)
