Method, system and storage medium for accessing local area network equipment by using domain name

Abstract

The invention discloses a method, a system and a storage medium for using a domain name to access a local area network device. The method includes: assigning a unique identifier to a target device in the local area network, and using the unique identifier to generate a URL containing a specific domain name; the target The device sends its own LAN IP address and a specific authorization code or feature code to the Internet server; the client accesses the target device through the URL, and the Internet server returns request response information to the client; the The client uses the request response information to access the target device. The invention dynamically registers the local area network IP address of the target device to the Internet server through the unique identification, and redirects the client program to the local area network IP address of the target device through the Internet server when the DNS interception condition is not met.

Description

technical field [0001] The invention relates to the field of local area network device access, in particular to a method, system and storage medium for accessing local area network devices by using a domain name. Background technique [0002] The Domain Name System (DNS for short) is a distributed database that maps domain names and IPs to each other. DNS resolution is an internal service that points the domain name to the web space IP, and can easily access the website through the registered domain name. People are used to memorizing domain names, but machines only recognize IP addresses. There is a one-to-one correspondence between domain names and IP addresses. The conversion between them is called domain name resolution. Enter the IP address in the browser to browse the website, and you can also enter the domain name to query the website. Although the obtained content is the same, the calling process is different. Entering the IP address directly calls the content from ...

AI Technical Summary

Problems solved by technology

[0008] However, when the client program does not use the DNS service of the target device in the LAN, DNS interception will not succeed

But all do not have the solution to the above-mentioned problem in above-mentioned patent application

When the DNS interception is unsuccessful, the specific domain name will point to the server on the Internet, and the target device user will not be able to easily obtain the LAN IP address of the target device, so that they will not be able to directly access the target device
