Problems solved by technology

[0004] Since the DNS server is very strict about DNS hijacking and attacks, adopting the above scheme means that the source port of the local message remains unchanged, and the destination port is 53. If the network service is obtained with high intensity for a long time, the DNS server will If it is misjudged as a DNS attack message, it will no longer reply to a normal dns request message, resulting in the failure of the user's network service.

Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0050] The embodiment of the present application discloses an address resolution method, which reduces misjudgment by the DNS server and ensures normal network services.

[0051] see figure 1 , a flow chart of an address resolution method shown according to an exemplary embodiment, as shown in figure 1 shown, including:

[0052] S101: Receive the address resolution request of the target device through the target lan port, and create a session channel corresponding to the address resolutio...

Abstract

The invention discloses an address resolution method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: receiving an address resolution request of target equipment through a target lan port, and creating a session channel corresponding to the address resolution request; sending the address resolution request to a DNS server by using a session channel; receiving an address resolution result of the DNS server through the session channel, and returning the address resolution result to the target device. According to the address resolutionmethod, a session channel for each address resolution request is created, the source port of each address resolution request is randomly selected in the router, and under the condition that a large number of address resolution requests are sent to the DNS server, the DNS server does not misjudge the DNS attack due to the fact that the source ports of all the address resolution requests are not completely the same, so the smoothness of network service is ensured.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, relates to an address resolution method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] The DNS (full name in Chinese: Domain Name System, full name in English: Domain Name System) server is a distributed database that maps domain names and IP (full name in Chinese: Internet Protocol, full name in English: Internet Protocol) addresses. Mapping relationship between IP addresses. Therefore, when the user needs to obtain network services through the client, he only needs to enter the domain name of the server that can provide the corresponding network service in the client, without having to memorize complicated IP addresses, so that the user can easily access the corresponding server through the client. local server and obtain the required network services. [0003] Most of the related technologies adopt a ...
