Embodiment Construction

[0133] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0134] The embodiment of the present invention provides a detection method for the IP address of the DNS egress server, which can be applied to figure 1 In the network framework shown. The network framework includes client, local DNS and detection server. The embodiment of the present invention supports multiple detection methods, including a domain name query detection method and an http (hypertext transfer protocol, hypertext transfer protocol) detection method. The specific detection process is as follows. The client is used to send a domain name resolution request including a detection domain name to the local DNS. The detection domain name is a domain name that cannot be resolved by the local DNS. The detection domain name is a ...

Abstract

The invention discloses DNS (Domain Name System) export server ip address detection methods and system. A method comprises the steps that clients send domain name resolution requests comprising detection domain names to a local DNS; after DNS export servers in the local DNS determine that the detection domain names cannot be resolved, detection requests comprising the detection domain names are sent to a detection server; the detection server obtains export ip addresses of the DNS export servers based on the detection requests; the detection server sends an ip address of the detection server to the local DNS; after the local DNS receives the ip address, the ip address is sent to the clients; the clients send access requests comprising the detection domain names to the detection server based on the ip addresses; and the detection server sends detection results comprising the export ip addresses to the clients based on the access requests. According to the method and the system, users can obtain the export ip addresses by carrying out preset domain names at the clients through utilization of specific commands. Operation is convenient and rapid. Communication cost can be reduced. Detection efficiency of the export ip addresses is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for detecting the IP address of a DNS egress server. Background technique [0002] When a client accesses a website through a domain name, it first needs to perform domain name resolution through the local DNS (Domain Name System, Domain Name System) to obtain the ip address of the website, and then access the ip address. The local DNS is usually a cluster, including many DNS servers. When performing domain name resolution for users, the DNS server that actually provides services, that is, the DNS egress server is not necessarily. [0003] In actual operation, if the local DNS configuration is wrong, for example, the local DNS configured by the client in area A is the DNS of area B, problems such as website inaccessibility or slow access may occur. Therefore, when troubleshooting this problem, it is necessary to find the IP address of the DNS egress server ...
