a.k.a. Internet Protocol version 6, IPng, Internet Protocol next-generation
An Internet Protocol (IP) designed as an evolutionary step from IPv4, it can be installed as a normal softwareupgrade in internet devices and is interoperable with the current IPv4. Its deployment strategy is designed to lack any dependencies.
Also known as IPng (pronounced "I-P next-generation"), IPv6 is designed to run well on high-performance networks while remaining efficient for low-bandwidth networks. In addition, it provides a platform for new Internet functionality that will eventually be required. It is intended to support Internet traffic for many years into the future by providing enhancements to the existing IP service.
