Abstract

The invention discloses a network access method and device for a mobile terminal. Wherein, the method includes: judging whether the domain name of the authentication server is hijacked according to the indication of the authentication request applied on the mobile terminal, and the mobile terminal connects to the CDN server of the data center through the authentication server; In the case of being hijacked, judge whether the domain name of the CDN server has been hijacked; if it is judged that the domain name of the CDN server has not been hijacked, use the CDN server as the proxy server of the mobile terminal; when the application on the received mobile terminal initiates an access target When a website access request is made, the proxy server resolves the first IP address corresponding to the domain name information in the access request, and the mobile terminal accesses the target website through the first IP address. The invention solves the technical problem in the related art that the mobile terminal cannot access the target website due to the DNS server.

Description

technical field [0001] The present invention relates to the field of the Internet, in particular to a method and device for network access of a mobile terminal. Background technique [0002] The Domain Name System (DNS for short) is a distributed database on the Internet that maps between domain names and IP addresses, enabling users to access the Internet more conveniently without remembering the IP numbers that can be directly recognized by machines. string. When the user enters the domain name on the client computer to initiate access locally, it will first query the local DNS server to resolve the domain name, and then answer the query through its own cached information, or query or contact other DNS servers on behalf of the client computer and finally return The IP address corresponding to the domain name. Clients (such as mobile phones, tablets and other mobile terminals) generally use the default DNS server address. This server is generally set up by domestic operato...
