Abstract

The invention discloses an access method for an IPv6 client to an IPv4 server. Through a stateless IPv4 / IPv6 address and protocol translation method, the public IPv4 address of the IPv4 server is mapped into a specific IPv6 address, any IPv6 address of the IPv6 internet is mapped into an IPv4 private address 10.0.0.0 / 8 through a one-way function, and the mapping relation is recorded so as to form a mapping relation table, so that any IPv6 address of the IPv6 internet can get access to the IPv4 server at no state, the stateless translation technology keeps the mapping unique, extendable and traceable, under the condition that the mapping relation table is generated and is valid, bi-directional communication is supported, and the transition from IPv4 to IPv6 is effectively promoted.

Description

technical field

[0001] The invention relates to the technical field of computer network communication, in particular to a method for an IPv6 client computer to access an IPv4 server. Background technique

[0002] Currently, the fourth version of the network protocol IPv4 widely used on the Internet has an addressing range of only 2 32 , that is, 4.3 billion addresses, which have been allocated at present. In order to solve the problem of insufficient IPv4 addresses, the Internet Engineering Task Force (IETF for short) designed the sixth version of the network protocol IPv6, and its addressing range is 2 128 , can completely solve the problem of insufficient IPv4 addresses.

[0003] However, due to various reasons, the IPv6 protocol is incompatible with the IPv4 protocol, and the interconnection and intercommunication between the two cannot be realized. Therefore, a method or technology is needed to realize the transition from IPv4 to IPv6. The industry has tried to use th...
