Address switching method and apparatus, domain name system and electronic device

Abstract

The embodiment of the invention relates to an address switching method and apparatus, a domain name system and an electronic device. The method comprises the following steps: a center control server receives a fault message sent by a network server that is faulty in a first area, and sends the fault message to at least one detection device in the first area; the detection devices respectively detect all network servers within the preset area excluding the first area and respectively collect network service information corresponding to the network servers; the center control server screens at least one to-be-selected network server corresponding to the network service information satisfying a preset condition according to the network service information corresponding to the network servers; and a DNS configuration management server separately modifies the IP addresses of the network servers that are faulty in the first area into one of the IP addresses of the to-be-selected network servers. By application of the address switching method and apparatus provided by the embodiment of the invention, the condition of the client accessing the network service can be known more accurately in more real time, thereby ensuring the availability of the network servers on the client.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an address switching method, device, domain name system and electronic equipment. Background technique [0002] Domain Name System (Domain Name System, DNS) is a core service of the Internet. As a distributed database that maps domain names and IP (Internet Protocol, Internet Protocol) addresses to each other, it enables users to access the Internet more conveniently without using To remember the IP number string that can be read directly by the machine. For a network service with a large number of users, the DNS system generally performs load balancing operations, that is, configures a series of different IP addresses for users in different regions, and each IP address corresponds to a network server. Users access the same DNS, which reduces the load and reduces the path, which is conducive to improving the access speed, and also reduces the targeted attack and reduces the...

Problems solved by technology

[0004] However, the inventor found in the process of implementing the present invention that at least the following problems exist in the prior art: when the DNS service of a certain area fails, the IP address of this area is replaced by the IP address of other areas, but because there is no guarantee The replaced IP address in the other area can provide normal network services, resulting in the loss of network services after replacement
