Abstract

The invention provides a domain name system resolution configuration method, device and system. Involved in the Internet field; solved the problem of DNS resolution failure caused by inapplicable configuration files. The method includes: the detection server uses the simulated representative IP address in the preset configuration area list to perform a domain name resolution request for all service domain names in the preset coverage scheme domain name list, and obtains IP addresses of all business servers according to DNS configuration files. , the coverage plan domain name list includes all service domain names and the corresponding relationship between the access IP source area and the service server IP address to which the corresponding service domain name is resolved, and the area list includes the access IP source area and the corresponding simulated representative IP address; The detection server detects whether the IP addresses of all the service servers fail; and updates the DNS configuration file according to the detection results of the IP addresses of all the service servers. The technical solution provided by the invention is applicable to DNS, and realizes a real-time discovery mechanism for service server failures.

Description

technical field [0001] The invention relates to the Internet field, in particular to a domain name system (DNS) resolution configuration method, device and system. Background technique [0002] The DNS server selects a business server according to the user's access request, and returns its IP address to the user, but due to various reasons, the DNS server may resolve the domain name to the IP address of the invalid business server. For example, the IP address corresponding to the domain name A record configured on the DNS server is inaccessible due to a fault, or the customer source is changed but not notified in time. Such a failure of the DNS server cluster has caused great damage to the user's experience in accessing services. [0003] In the prior art, when the number of DNS servers providing services is large, the designated IP list is generally detected by the detection server of the central dispatching system to determine the availability of the IP address. When the ...
