Abstract

The invention discloses a method for analyzing a DNS. The method for analyzing the DNS comprises the steps that when a browser side monitors that DNS analysis of a first webpage is wrong, an original DNS address of a current terminal is reset to be an appointed DNS address; a DNS analysis request of the first webpage is sent to the appointed DNS address, wherein the domain name of the first webpage is included in the DNS analysis request; an appointed DNS is used for analyzing one or more IP addresses corresponding to the domain name of the first webpage according to the DNS analysis request; the IP addresses returned by the appointed DNS are received; when it is ensured that the IP addresses returned by the appointed DNS are legal through verification, the legal IP addresses are extracted. The probability of successful DNS analysis can be greatly increased, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of browsers, in particular to a DNS resolution method, a DNS resolution device, and a browser. Background technique [0002] In the application of the Internet, the domain name and IP (Internet Protocol, the protocol for interconnection between networks) addresses are indispensable, because people must use the domain name and IP address of the website to find and log in when visiting the website. DNS (Domain Name System), also known as the domain name system (or domain name server), is used when searching for domain names and IP addresses in existing technologies. DNS is used for domain name resolution, assigning domain name addresses and IP addresses to hosts on the Internet. That is to say, when a user requests DNS for domain name address resolution, the system will automatically convert the domain name address into an IP address. In practice, any domain name has at least one DNS to resolve the d...
