A method and device for offline domain name resolution

Abstract

The invention discloses an off-line domain name analysis method and device. Wherein the method comprises the following steps: A, judging the current network status and detecting the DNS server, and sending DNS re-analysis instructions and / or IP redirection instructions when the network is abnormal; B, resetting the domain name associated with the network abnormal part Analysis; C. Redirect IP access to the network exception output of the network exception module; D. Provide network access information prompts and provide network services locally. The device includes a network judgment module, a DNS reanalysis module, an IP redirection module and a local network module. The present invention can also provide reliable and optimal domain name resolution results and network jump results for networked terminals under various network conditions, especially when the network is abnormal, so as to improve user network access experience.

Description

technical field [0001] The invention relates to an off-line domain name resolution method and device, which are used to avoid poor online experience caused by network failures, and belong to the field of network communication. Background technique [0002] At present, with the explosive growth of mobile Internet, terminal equipment network access is becoming more and more frequent, and users' online experience is becoming more and more sensitive. However, the network environment is complex, and the network requests of terminals are greatly tested. In the application environment where the user is connected to the WiFi network through the 3G / 4G mobile network while the user is mobile, the stability of the network connection is especially tested. [0003] The domain name resolution in the basic link that affects the Internet experience is often subject to the impact of bandwidth. Unstable factors such as signal weakening and interference that are prone to occur in mobile netwo...

Problems solved by technology

For example: 1. The domain name cannot be resolved normally after the network communication is interrupted due to network disconnection or false wireless network connection, which eventually leads to a white screen when the user's smart terminal is connected to the Internet and accesses the external network; 2. The domain name is caused by incorrectly entering the URL and other reasons It cannot be parsed normally, which eventually leads to a white screen when the user's smart terminal accesses the Internet after connecting to the Internet; 3. When the network delay is large, the domain name can be resolved but the actual network effect is extremely poor, which eventually leads to the user's smart terminal accessing the Internet after connecting to the Internet 4. When the network is not smooth enough, the browser uses the acceleration engine to automatically resolve the domain name and automatically complete the jump, which will eventually cause the user's smart terminal to access the Internet after connecting to the Internet and a page will appear. Facing a blank screen or displaying that the webpage cannot be opened
