Problems solved by technology

This method filters irrelevant data information to a certain extent, but it is filtered after receiving data, which needs to consume a lot of traffic
The other is router filtering. Router filtering is to filter the corresponding data content by checking the Internet Protocol (IP). At present, 80% of routers support IP filtering, but the IP filtering of routers is limited by the number. Generally, one router Only 8 IPs can be filtered at most, and users need to manually add the IPs that need to be filtered

Abstract

The invention discloses a method and equipment for filtering network data content by DNS, relates to the technical field of communication, can not be limited by the number of IPs when filtering network data content, and saves traffic. The main technical solution of the present invention is: when a terminal device requests network data content through a webpage, the DNS server obtains the webpage address of the requested webpage and resolves the webpage address into a network protocol IP address. The IP address list; the DNS server obtains the IP address list corresponding to the terminal device that needs to be filtered, and matches the resolved IP address with the IP address in the IP address list that needs to be filtered corresponding to the terminal device ; If the matching is successful, the resolved IP address is filtered out, and the resolved IP address is not fed back to the terminal device. The invention is mainly used in the process of filtering network data content.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for DNS filtering network data content. Background technique [0002] With the development of the Internet, network data floods, and a lot of data information that is unhealthy or that the viewer does not want to obtain is input, which makes the user's network use extremely inconvenient. In order to filter out some unhealthy, unnecessary and unwanted network data information, various filtering methods are used in the prior art, and browser filtering is commonly used. Browser filtering is to output the information requested by the user in the browser. Make a judgment at the time to determine whether to display the received data content on the page. This method filters irrelevant data information to a certain extent, but it is filtered after the data is received and needs to consume a lot of traffic. The other is router filtering. Router filtering is ...
