Cloud service-based IPv6 (internet protocol version 6)/IPv4 (internet protocol version 4) translation method with communication initiated by IPv6 party

Abstract

The invention provides a cloud service-based IPv6 (internet protocol version 6) / IPv4 (internet protocol version 4) translation method with communication initiated by an IPv6 party, and relates to the technical field of a computer network. The method is used for realizing the service that an IPv6 user or a dual-stack user can seamlessly initiate the information resource for accessing the IPv4; a cloud service data center is provided with an information resource data base, a domain name analysis server, a stateless IPv4 / IPv6 translator and a stateful IPv6 / IPv6 translator, wherein the stateless IPv4 / IPv6 translator and the stateful IPv6 / IPv6 are connected with each other in series; a translation algorithm of the stateless IPv4 / IPv6 translator is used for translating an IPv4 address which is reserved for accessing a pure IPv4 server from an IPv6 network into a special IPv6 address which is embedded with the IPv4 address and uses an operator prefix; a translation algorithm of the stateful IPv6 / IPv6 is used for dynamically mapping any IPv6 addresses of the user into the special IPv6 address which is embedded with the IPv4 address; and the domain name analysis server is used for answering a domain name analysis request of the user, and returning an A record or an AAAA record for the user according to the content of an information resource data base, therefore, the pure IPv4 user of the dual-stack user can initiate the information resource for accessing the pure IPv4 by the IPv6.

Description

IPv4 / IPv6 translation method for communication initiated by IPv6 party based on cloud service Technical field The present invention relates to the technical field of computer networks, in particular to an IPv4 / IPv6 translation method based on cloud services that initiates communication by an IPv6 party. Background technique The Internet has become the most important information infrastructure in the world, but the addressing range of the IPv4 address of the fourth version of the Internet protocol widely used on the Internet is only 232, that is, 4.3 billion addresses. The current IPv4 address allocation is about to be completed. At present, the absolute number of netizens in China has become the world's first, but the penetration rate of the Internet is only 30%, far lower than the level of developed countries (70%). At the same time, on average, each Chinese netizen has only 0.6 IPv4 addresses. Therefore, for China, IPv4 addresses cannot meet the demand. This problem is ver...

AI Technical Summary

Problems solved by technology

2. IPv6 network performance issues

Switching to IPv6 under the condition that the current IPv6 technology is not yet fully mature will bring about a decline in user experience

3. Host address configuration problem

Therefore, providing users with suitable network services is a huge challenge
