Then the main document was published in December 1995: RFC1883 'Internet Protocol, Version 6 (IPv6) Specification'. The History of IPv6 started in 1994-1995 with documents such as: RFC1719 'A Direction for IPng', RFC1726 'Technical Criteria for Choosing IP The Next Generation (IPng)' and RFC1752 RFC1752 'The Recommendation for the IP Next Generation Protocol'. Extensibility: Improved support for options / extensions.Enhanced support for multicast and QoS.Streamlined header format and flow identification.End-to-end security, with built-in, strong IP-layer encryption and authentication.More efficient and robust mobility mechanisms.Server-less autoconfiguration ('plug-n-play') and reconfiguration.Ĭonsequently, the design of IPv6 was an opportunistic way to improve the Internet, with new benefits such as: There may be alternative technical solutions, such as NAT (Network Address Translation), but they won't work so easily to allow this growth.

This, combined with new 'always-on' access technologies such as xDSL, cable, ethernet-to-the-home, were increasing the appetite for new devices and new users. This need arose from fast Internet growth: billions of new devices (cell phones, PDAs, appliances, cars, etc.), and billions of new users (China, India, Latin America). IPv6 was initially designed with a compelling reason in mind: the need for more IP addresses. IPv6 is the 'next generation' protocol designed by the IETF to replace the current version of Internet_Protocol, IP Version 4 or IPv4. IPv6 is short for 'Internet Protocol version 6'.
