Method and system for controlling network connection

Abstract

The invention discloses a method and a system for controlling network connection. The method is characterized in that a server configures a corresponding IP address list based on the attribute of a user, one IP address list at least includes two IP addresses, and each IP address corresponds to one weight value; after receiving the network connection request of a client, the server searches one IPaddress list which is correspondingly configured through the attribute of the user, and returns the IP address list to the client; and after receiving the IP address list, the client sorts the weightvalues of an IP addresses in the IP address list from high to low, and successively tries to connect the IP address starting from the IP address with the highest weight value, if connection is successful, network communication is performed through the connection, and if the connection is unsuccessful, the client tries to connect the IP address with the lower weight value till that the connection is successful or all the IP addresses in the IP address list can not be connected. In the invention, the data updating efficiency of operation server can be increased and the fine control degree of a client network inlet is improved.

Description

technical field [0001] The present application relates to the field of computer internet, in particular to a method and system for controlling network connection. Background technique [0002] The Domain Name System (DNS, Domain Name System) is a distributed database on the Internet that maps domain names and Internet Protocol (IP) addresses to each other, enabling users to access the Internet more conveniently without having to remember what can be accessed The IP number string read directly by the machine. [0003] DNS hijacking, also known as domain name hijacking, refers to intercepting domain name resolution requests within the hijacked network range, analyzing the requested domain name, and releasing requests outside the scope of review, otherwise it will return a fake IP address or do nothing to make the request unresponsive. The effect is that a specific network does not respond or visits a fake URL. [0004] In order to avoid DNS hijacking, the current existing te...

Problems solved by technology

The domain name system is a system with multiple levels. Each level of DNS server will cache the data of the upper level. When updating, the data in the root level DNS server needs to be updated, and the lower levels will be updated level by level. Therefore, there will be a period of delay, and the update time of some small operators may be very long, which seriously affects the efficiency of scheduling

At the same time, due to the use of the operator's domain name system, it cannot be controlled individually for each user. It can only be divided by region and line, and the granularity is not fine enough.

[0006] At the same time, when a client requests a network entry, it basically requests a network entry under a fixed domain name. When the client will cause future upgrades and changes, such as a change in the domain name, compatibility with the old version of the client must always be considered. , resulting in unnecessary additional costs
