Abstract

The invention discloses a network access method and a device for a mobile terminal. The method comprises steps: whether the domain name of an authentication server is hijacked is judged according to an instruction for an authentication request for an application on the mobile terminal, and the mobile terminal is connected with a CDN server in a data center via the authentication server; in a condition in which the domain name of the authentication server is judged not to be hijacked, whether the domain name of the CDN server is hijacked is judged; in a condition in which the domain name of the CDN server is judged not to be hijacked, the CDN server serves as a proxy server for the mobile terminal; and when an access request for target website access initiated by the application on the mobile terminal is received, a first IP address corresponding to the domain name information in the access request is analyzed through the proxy server, and the mobile terminal accesses the target website via the first IP address. The technical problem that the mobile terminal can not access the target website due to a DNS (Domain Name System) server in related technology is solved.

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...
