Problems solved by technology

For general pure WEB access applications, DNS interception has little impact on users, but for URL access initiated through the self-developed application background, the impact on users will appear, affecting users and causing abnormalities such as application access failure or update failure Happening
[0003] In the prior art, most of the methods to solve the interception are to use the proxy server to jump or find the operator to appeal, which requires high technical ability of the end user or controllable time, which brings great troubles to the end user

Embodiment Construction

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] figure 1 For the flowchart of the method for preventing DNS interception according to the present invention, reference will be made below figure 1 , The method for preventing DNS interception of the present invention will be described in detail.

[0019] First, in step 101, the application initiates a URL test, confirms whether the returned result is correct, and judges whether there is a DNS interception phenomenon. If there is DNS interception, proceed to the next step; otherwise, proceed to step 103.

[0020] In step 102, an IP URL address is randomly selected from the configured address pool for testing, and a node with normal feedback is found through the IP URL te...

Abstract

A method for avoiding DNS cutting comprises the following steps: determining whether there is a DNS cutting phenomenon or not, and finding out nodes having normal feedback; initiating a formal URL request, and completing an access process; and storing access nodes. The method for avoiding DNS cutting is the most transparent existence for final users, and users can solve a DNS cutting problem with no need for performing any operation; and the failure conditions caused by an unstable regional network are solved through a multi-test mode, and an application providers can improve the success rate through mode of increasing an address pool and application local buffer memory.

Description

Technical field [0001] The invention relates to the technical field of Internet website addresses, and in particular to a method for preventing DNS interception. Background technique [0002] With the rapid development of the Internet, each telecom operator’s own interests will intercept the DNS of their broadband access terminal users, so that when users access the target web page, they will first visit the page designated by the operator and then jump to Landing page. DNS interception has little impact on users for general pure WEB access applications, but for URL access initiated through the backend of self-developed applications, the impact on users will be displayed, affecting users and causing abnormalities such as application access failure or update failure Happening. [0003] In the prior art, most of the methods to solve the interception are to use a proxy server to jump or find an operator to appeal, which requires high technical capabilities of the end user or control...
