The Network Migration Gateway is the first multi-functional and high-secure solution to migrate to IPv6 networks. The driving need to implement the next-generation Internet Protocol version 6 (IPv6) in enterprise networks, cloud solutions and hosted environments requires a migration path. The Network Migration Gateway is a technology to connect legacy IP infrastructures to latest generation IPv6 networks, state-of-the-art IPv6 networks to the traditional IPv4 Internet, and to provide dynamic protection with the IKEv2 IP security mechanism.
IPv4 addresses exhaustion and IPv6
The current infrastructure of the Internet is based on its underlying TCP/IP protocol suite – the Internet Protocol version 4. The IPv4 protocol uses a 32bit address space, which limits the Internet to a possible maximum of 4,294,967,296 (2^32) unique addresses, for connected systems, servers or routers. The next-generation protocol IPv6 introduces extended functionality and a 128bit address space, or 340, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 456 (2^128) unique addresses.
– IPv4 addresses exhausted – In February 2011, the Internet Assigned Numbers Authority (IANA) announced the exhaustion of the primary IPv4 address pool. The rapid growth of global Internet users and an increasing need for unique IP addresses exhausted the address space about 30 years after the standardization of IPv4 in 1981
– IPv6 for compliance – Some governments started to require IPv6 compliance for any new systems connected to their networks. For example, the US Government requires IPv6 with their recent USGv6 standard by the National Institute of Standards and Technology (NIST).
Solving the IPv6 Migration Problem
Many businesses are facing the problem of migrating their networks and solutions to IPv6. The common approach of running “dual-stack” configurations with IPv4 and IPv6 on the same clients, servers and routers doesn’t solve the migration problem. It is either IPv4 or IPv6 or both in parallel. Many legacy systems don’t even support IPv6 and cannot be replaced or upgraded in the next number of years. A significant investment is required to upgrade all systems, products and solutions to IPv6 but it is required to meet the compliance criteria and to drive the future business. The Network Migration Gateway closes the gap and opens a valuable migration path.
