Abstract

The invention provides a domain name system resolution configuration method, device and system and belongs to the Internet field. With the domain name system resolution configuration method, device and system adopted, the problem of DNS resolution failure caused by the inapplicability of a configuration file can be solved. The method includes the following steps that: a detection server requests for domain name resolution on all service domain names in a preset coverage scheme domain name list by using analog representative IP addresses in a preset configuration area list, and performs resolution and obtains the IP addresses of all service servers according to a DNS configuration file, wherein the coverage scheme domain name list includes all service domain names and corresponding relationships between access IP source regions and service server IP addresses to which the corresponding service domain names are resolved, and the region list includes the access IP source regions and corresponding analog representative IP addresses; the detection server detects whether the IP addresses of the all service servers malfunction; and the DNS configuration file is updated according to the detection result of the IP addresses of all the service servers. The domain name system resolution configuration method, device and system of the technical schemes provided by the invention are applicable to DNSs. With the domain name system resolution configuration method, device and system adopted, a mechanism for discovering the failure of the service servers is realized.

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 ...
