Problems solved by technology

[0007] However, since each node in the authoritative DNS server corresponds to a pre-divided IP address segment, the granularity of the IP address is relatively coarse. When the entry node corresponding to the IP address segment or the parent node of the entry node fails, domain name resolution will be caused. The results are biased, reducing the accuracy of domain name resolution

Abstract

The embodiment of the invention provides a domain name resolution method and apparatus, an electronic device, and a readable storage medium. The method comprises the following steps: obtaining a domain name and a source IP address carried in a domain name resolution request message sent by a local DNS server, querying domain name resolution information corresponding to the domain name in a presetprivate mapping table according to the domain name, and when the domain name resolution information corresponding to the domain name is queried, sending a resolution response message carrying the domain name resolution information to the local DNS server corresponding to the source IP address. By adoption of the domain name resolution method and apparatus, the electronic device, and the readable storage medium provided by the embodiment of the invention, the domain name resolution information can be directly resolved through the domain name, fine-grained analysis is performed on the domain name resolution request, the domain name resolution accuracy is improved, and the time consumed for resolving the domain name is shortened.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a domain name resolution method, device, electronic equipment and readable storage medium. Background technique [0002] DNS (Domain Name System, Domain Name System), a distributed database on the Internet that maps domain names and IP (Internet Protocol, a protocol for interconnection between networks) addresses, enables users to access the Internet more conveniently without having to remember A string of IP numbers that can be read directly by a machine. The process of obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution), and the network host that performs domain name resolution is called a DNS server. Through the DNS server, the IP address of the required site or resource can be obtained, and then the site or resource can be accessed. [0003] ICP (Internet Content Prov...
