IPv6 and IPv4 conversion method applied to network migration

Abstract

The invention discloses an IPv6 (Internet Protocol Version 6) and IPv4 (Internet Protocol Version 4) conversion method applied to network migration, which is characterized by comprising the following steps of: 1, determining related information which needs to provide an IPv6 service to the outside and comprises an original IPv4 public network address corresponding to the service and an intranet server address of the original IPv4 public network address; step 2, address conversion of the IPv6 and the IPv4 is carried out; and step 3, a reverse proxy is arranged in the current network environment, an IPv6 address is configured in the upper reverse proxy, the reverse proxy starts source address conversion, and an internal proxy address is an internal network address mapped by the original IPv4 public network address. According to the invention, the relevance between the IPv6 service and the original service is enhanced through the address conversion rule, the cost is low, and the management and maintenance difficulty of a later system is reduced. The method can be applied to the process of migrating from an IPv4 network to an IPv6 network of an enterprise, and can also be applied to the situation that the enterprise needs to provide IPv6 services for customers.

Description

technical field [0001] The application relates to an IPv6-to-IPv4 conversion method applied in network migration, and belongs to the technical field of IPv6 network. Background technique [0002] At present, the global IPv4 addresses have been exhausted, and all about 4.3 billion IP addresses have been allocated. There is no more IPv4 to be allocated to Internet service providers and other large-scale network infrastructure providers. In the Internet age, the lack of addresses will Greatly affect the development of society. The IPv6 address was created to solve this problem, and its 128-bit length greatly increases the number of addresses. However, the process of transitioning to IPv6 is not easy, and it needs the support of operators, user terminals, and enterprise server terminals to realize it. At present, the backbone networks of China Telecom, China Mobile, China Unicom and other operators have all supported IPv6; on the user side, including home broadband and mobile ...

AI Technical Summary

Problems solved by technology

The reason is that the enterprise network generally adopts a pure IPv4 structure, and IPv4 and IPv6 cannot communicate directly. If they want to migrate to IPv6, the enterprise needs to rebuild an IPv6 system on the original basis. If the existing equipment does not support IPv6, it needs to be purchased separately.

Secondly, enterprises also have concerns that the migration process may affect existing businesses and cause losses

Finally, the independence of IPv4 and IPv6 dual systems may cause conflicts in business logic, difficulty in operation and maintenance, and chaotic management.

High difficulty and high cost lead to low willingness and slow progress of enterprises to migrate to IPv6
