IP version 6

Internet Protocol version 6 (IPv6) is the next generation Internet protocol layer packet switched internetworks and the Internet. IPv4 is currently [update] dominant Internet Protocol version and was the first to receive widespread use. In December 1998, Internet Engineering Task Force (IETF) has designated IPv6 as the successor to version 4, the publication of a specification Standards Track, RFC 2460.

In December 2008, while celebrating his 10th anniversary as a standards track protocol, IPv6 was only in its infancy in terms deployment around the world in general. A recent study [1] by Google indicates that the penetration is still less than one percent of Internet traffic across the country. The leaders are Russia (0.76%), France (0.65%), Ukraine (0.64%), Norway (0.49%) and USA (0.45%). While Asia leads in terms of absolute numbers of implantation, the relative penetration is lower (eg, China: 0.24%). IPv6 is implemented in all major operating systems in use in commercial, consumer and home environments. According to the study takes into Mac OS IPv6 penetration of 2.44% followed by Linux (0.93%) and Windows Vista (0.32%) [2].

IPv6 has a much larger address space than IPv4. This results from the use of a 128-bit address where IPv4 uses 32-bit only. The new address space, therefore, supports 2128 (about 3.4 × 1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the need for network address translation (NAT). NAT gained widespread deployment as an effort to alleviate the exhaustion of IPv4 address.

IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router advertisements) when changing supplier of Internet connection. The size of the subnet IPv6 was standardized by fixing the size of the host identifier portion of a 64-bit address to facilitate an automatic mechanism to form the host identifier Link Layer information Addressing media (MAC address).

Network security is integrated into the architectural design of IPv6. Internet Protocol Security (IPSec) was originally developed for IPv6, but found widespread deployment optional first IPv4 (where she was back to engineering). The Implementation of IPv6 specifications mandate IPsec as a key requirement for interoperability.
