Parsing method of network domain

Abstract

The invention discloses a parsing method of a network domain. The domain comprises a first domain and a second domain. The parsing method comprises the following steps: parsing the first domain into a first network address in a first network system; searching a first network node corresponding to the first network address according to the first network address in the first network system; and parsing the second domain to be a second network node address in a second network system, wherein a domain parsing system of the second network system is independent of a domain parsing system of the first network system. The domain address parsing structure of an internal network is independent of the domain address parsing structure of a WWW (World-Wide-Web), therefore, an IP (Internet Protocol) address of the internal network cannot occupy IP address resource in the WWW.

Description

technical field [0001] The invention relates to a computer network domain name analysis method, in particular to an industrial internet domain name analysis method. Background technique [0002] In the existing World Wide Web (Internet), each node of the network (including: website, server, host, etc.) has a fixed (or static) IP address corresponding to it. According to the protocol, the IP address is a string of fixed-length, segmented Arabic numerals, such as 192.168.10.3. But this kind of IP address represented by numbers is not easy for people to remember. For the convenience of memory, the World Wide Web uses a string of English letters (or letters or characters in other languages), numbers, or a mixture of the two to form a domain name (Domain Name) corresponding to an IP address. For example, "www.sina.com", "www.sipo.gov.cn", "www.fudan.edu" are all easy to remember domain names. [0003] In this way, when a user enters a domain name on the browser of his computer...

AI Technical Summary

Problems solved by technology

If a static IP address is assigned to each internal network node, it is not only impossible from the perspective of resources, but also very expensive

[0006] 2. Cannot meet the safety requirements

Although some large-scale LAN internal nodes adopt domain name management, all nodes in the entire network are at the same level and do not distinguish between levels

Moreover, the address resolution method in the World Wide Web generally adopts the ARP address resolution protocol. When there are many layers between multiple remote access nodes in the network, the ARP address resolution protocol cannot realize the search of remote access nodes with lower levels.

[0008] 3. The resolution efficiency of the existing IP address is not high. If there are hundreds or even thousands of
