Method for translating Internet protocol version 4 (IPv4)/Internet protocol version 6 (IPv6) initiating communication by using IPv4 based on cloud service

Abstract

The invention discloses a method for translating an Internet protocol version 4 (IPv4)/Internet protocol version 6 (IPv6) initiating communication based on cloud service by using the IPv4, which relates to the technical field of computer networks. In the method, an information resource database and a domain name resolution server are installed in a cloud service data center; simultaneously, a serial stateless IPv4/IPv6 translator and an IPv4/IPv6 translator configured through the information resource database are installed; an address translation algorithm of the stateless IPv4/IPv6 translator is used for translating an IPv4 address reserved for accessing a pure IPv6 service from an IPv4 network into a special IPv6 address into which the IPv4 address is embedded and an operator prefix is used; an address translation algorithm of the IPv4/IPv6 translator is used for mapping an IPv6 address which corresponds to a pure IPv6 information resource into the special IPv6 address into which the IPv4 address is embedded; and the domain name resolution server is used for returning a record A to a user in response to a domain name resolution request of the user according to a mapping relation. Therefore, an IPv4 user can initiate access to the information resource of a pure IPv6, and the aim of communicating the IPv4 with the IPv6 is fulfilled.

Description

IPv4 / IPv6 translation method initiated by IPv4 party based on cloud service technical field The invention relates to the technical field of computer networks, in particular to a cloud service-based IPv4 / IPv6 translation method in which communication is initiated by an IPv4 party. Background technique The Internet has become the most important information infrastructure in the world, but the addressing range of IPv4, the fourth version of the network protocol widely used on the Internet, is only 232, that is, 4.3 billion addresses, and the IPv4 addresses are about to be allocated. At present, the absolute number of Internet users in China has become the first in the world, but the penetration rate of the Internet is only 30%, which is far below the level of developed countries (70%). At the same time, each Chinese Internet user has only 0.6 IPv4 addresses on average. Therefore, for China, IPv4 addresses cannot meet the demand. This problem is very serious for India and o...
