Embodiment Construction

[0027]In the prior art, for domain names that have been accelerated by CDN, the open source software BIND is usually used to perform DNS scheduling, mainly through the view function of BIND. When receiving a domain name resolution request, first determine which view the source IP of the domain name resolution request belongs to, for example, the IP of Zhejiang Telecom is 115.233.237.1, and 115.233.237.1 is in the address range of 115.233.237.0 / 24, then it will enter the view For the configuration of cn_ct_zhejiang. If the source IP of the domain name resolution request does not match the view, return empty. After finding the view, match the domain (zone) according to the domain name to be resolved. For example, the domain name to be resolved x.y.com.cdn1.com matches the configuration of zone "cdn1.com", then it will go to the hosts file " / var / named / cdn1_cn_ct_zhejiang .hosts” to find the configuration of the domain name to be resolved. Returns empty if no zone matching the d...

Abstract

The invention discloses a DNS scheduling method, a domain name server and a computer readable storage medium, and the DNS scheduling method comprises the steps: obtaining a to-be-analyzed domain namefrom a domain name analysis request when the domain name analysis request is received; judging whether the domain of the domain name to be parsed belongs to a parsable domain range or not; when the domain of the to-be-parsed domain name belongs to a parsable domain range, judging whether configuration corresponding to the to-be-parsed domain name exists in a domain configuration file correspondingto the domain or not; when the domain configuration file has the configuration corresponding to the to-be-analyzed domain name, determining target configuration corresponding to the to-be-analyzed domain name, the target configuration corresponding to the to-be-analyzed domain name comprising an IP address of a target CDN server; and outputting the target configuration corresponding to the domainname to be resolved. According to the scheme, the domain name resolution efficiency can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of DNS scheduling, in particular to a DNS scheduling method, a domain name server, and a computer-readable storage medium Background technique [0002] Domain Name System (Domain Name System, DNS) is a core service of the Internet. DNS is a distributed database that maps domain names and IP addresses to each other. The IP address directly read by the machine, where the domain name must have a corresponding IP address. DNS is composed of resolvers and domain name servers. A domain name server refers to a server that saves the domain names and corresponding IP addresses of all hosts on the Internet and has the function of converting domain names to IP addresses. [0003] Content Delivery Network (CDN), by adding a new layer of network architecture to the existing Internet, publishes Internet content to the "edge" of the network closest to users, so that users can obtain the required content nearb...
