Method and system for controlling network connection

Abstract

The present application discloses a method and system for controlling network connections, including: the server configures a corresponding IP address list based on user attributes, an IP address list includes at least two IP addresses, and each IP address corresponds to a weight value ;After receiving the network connection request from the client, the server searches for a list of IP addresses configured corresponding to the user's attributes, and returns the list of IP addresses to the client; after receiving the list of IP addresses, the client follows the The weight values ​​of the IP addresses in the IP address list are sorted from high to low. Starting from the IP address with the highest weight value, try to connect to the IP address in turn. If the connection is successful, use this connection for network communication. If the connection is unsuccessful, try again Connect to the IP address with a lower weight value until the connection is successful or all the IP addresses in the IP address list fail to connect. The invention can improve the data update efficiency of the operation server and improve the fine control degree of the network entrance of the user.

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...

AI Technical Summary

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
