IPv6 also named IP-Next-Generation (IPng), designed by the IETF (The Internet Engineering Task Force) in 1994 to improve the performance of the current version Internet Protocol, IP Version 4 Internet protocol supports the interconnection of multiple networking technologies into a single, logical internetwork. IPv4 is used for nearly twenty years, begins to have problems mainly because of its growing shortage of addresses, which are needed by all new machines added to the Internet.  The purpose of IPng is to not only fix IPv4’s problems, such as addresses, routing and network auto-configurations and eventually replace IPv4, but also to run well on high performance networks as well as maintaining its efficiency for low bandwidth networks.
