IPv6-related technology has been developed for many years, countries generally attach importance to IPv6 deployment, and there is a trend of acceleration in recent years. As a basic resource, the importance of IPv6 address is needless to say. For enterprise network users, driven by the needs of 5G, Internet of things, mobile office and network security, it is a general trend for applications to gradually switch from IPv4 to IPv6. Last year, the two offices issued the "Action Plan for promoting the scale deployment of Internet Protocol version 6 (IPv6)", which put the deployment of IPv6 on the scale of domestic enterprise network users on the agenda.

At present, some enterprise network users have begun to deploy IPv6 services. How to select equipment and how to smooth business migration in IPv6 environment have attracted much attention. The new system can be fully considered at the beginning of planning and select devices that fully support IPv6. However, for scenarios with a large number of IPv4 existing network transformation requirements, users need to consider devices that support dual-stack, NAT64 and other excessive technologies, and consider the increased complexity of dual-stack scenarios, key equipment and key scenarios need to consider more testing, to reduce the impact of later compatibility and stability risks on the business. In addition, in addition to network equipment, security, application delivery with the ability to deploy under IPv6 is also critical. Secondly, how to achieve the smooth migration of business from IPv4 to IPv6 environment is a difficult point at the present stage, including IPv6 upgrade and verification of terminal, IPv6 transformation of network and IPv6 upgrade and verification of business system.

From the practice of Dipper, the construction of IPv6 experimental network, the gradual migration of services according to priority, and the mutual backup capabilities provided by IPv4 and IPv6 systems in the process of migration, in order to reduce the impact and impact of IPv6 transition on existing network services, which is a more reasonable choice for enterprise users at present. It is difficult to avoid the coexistence of IPv4 and IPv6 for a long time and gradually evolve into an IPv6 environment, so planning is the key. In addition, the problem of operation and maintenance management in the process of migration also needs to be considered. Users may face the simultaneous operation and maintenance of IPv6 and IPv4, as well as the migration of part of the business between the two networks, so the urgency of visualization and automation tools is very high. In view of the above problems, Dip products have fully considered IPv6, and plan to launch an one-stop solution for IPv6 migration to help enterprise network users overcome the difficulties of smooth migration and operation and maintenance.

IPv6 will inevitably bring a large number of new opportunities for basic IT systems, and if the policy support is sufficient, it can be said to be the biggest opportunity in the next 5-10 years. For the planning of IPv6 network construction in 2018, Dipp said that in the future, it will focus on the IPv6 transition and transformation of operators, governments and central enterprises, especially the network security construction opportunities and operation and maintenance needs of the government and enterprises in the IPv6 migration.
