Problems solved by technology

When the http / https page uses the IP as the address for redirection, the proxy access may fail because the adjusted IP is not in the routing table
In addition, because the method of obtaining domain names must rely on the HOST field, and currently only http and https protocols have HOST fields, this solution only supports http and https protocols, that is, this solution cannot be applied to more proxy scenarios

Embodiment Construction

[0048] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] An embodiment:

[0050] Please refer to figure 1 , figure 1 It is a flowchart of a domain name proxy method in the embodiment of the present invention. The domain name proxy method provided by this embodiment can be applied to a fake domain name resolution server, which can be set in a client (client computer), or can be set in a server such as figure 2 In the local router shown, or in other device...

Abstract

The invention discloses a domain name proxy method, device and equipment and a readable storage medium, and the method comprises the following steps: receiving and analyzing an application data flow transmitted by an application program in a client, and obtaining a forged IP address; querying a corresponding target domain name by using the forged IP address; wherein the forged IP address is an IPaddress fed back to the application program when the application program requests to analyze the target domain name; replacing the forged IP address with a target domain name in the application data stream to obtain a target application data stream; and sending the target application data stream to a proxy server. According to the method, after the IP address is forged, the target domain name canbe reversely found through the forged IP address, so that the method does not need to be limited by a transmission protocol, a large number of routing tables do not need to be added, and the drainageproblem in scenes such as discontinuous distribution of IP addresses of intranet resources can be solved.

Description

technical field [0001] The present invention relates to the field of computer and network technology, in particular to a domain name proxy method, device, equipment and readable storage medium. Background technique [0002] In the traditional DNS proxy solution, it is necessary to add a large number of routing tables to achieve traffic drainage. Too many routing tables will affect the system's operating efficiency and cause system crashes. [0003] At present, V2ray's sniffing technology (a network monitoring technology) intercepts all DNS (Domain Name System, domain name system) messages and responds with the same IP. Proxy access as an address. It can be seen that this solution does not need to add a large number of routing tables to achieve traffic drainage. When the http / https page uses the IP as the address for redirection, the proxy access may fail because the adjusted IP is not in the routing table. In addition, because the method of obtaining domain names must rel...
