Problems solved by technology

[0005] In view of this, the present invention provides a method, device and server for repairing webpages based on DNS polling. This solution can solve the problem that some webpages can sometimes be accessed normally due to the technology of load balancing through DNS polling, and sometimes But can not access the problem, so that users can access the web page more smoothly

Abstract

The embodiment of the invention discloses a method and a device for repairing domain name system (DNS) polling mode-based webpages and a server. The method comprises the following steps of acquiring domain names of reference resources in to-be-repaired webpages; inquiring a DNS resolution system to acquire all internet protocols (IP) which correspond to the domain names; verifying the availability of all the IPs, and marking available IPs; and randomly selecting one available IP when a DNS request of a client side for the resources under the domain names is received, and replying the client side by taking the IP as a resolution result. According to the method disclosed by the embodiment of the invention, the problem that certain webpages can be normally visited sometimes, but cannot be visited sometimes due to the technology that DNS polling serves as load balancing is solved, so that users can visit the webpages more fluently.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to a method, device and server for repairing web pages based on DNS polling mode. Background technique [0002] In today's society, people's lives are inseparable from web pages. Many activities in our lives, such as obtaining information online, communicating with friends, shopping online, etc., are increasingly happening on web pages. And DNS (Domain Name System, Domain Name Resolution System) is the first gateway for people to access web pages, so it is extremely important. [0003] Web pages are stored on servers on the Internet, and each server is identified by a dotted decimal IP, such as 202.96.128.166, which identifies a server. Since the dotted decimal IP is not conducive to people's memory, the concept of domain name was introduced. The domain name is equivalent to the alias of the machine, which can be resolved into IP through the domain name resolu...
