IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the primary need fornetwork address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.
IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router announcements) when changing Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the host identifier from Link Layer media addressing information (MAC address).
Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security (IPsec) was originally developed for IPv6, but found widespread optional deployment first in IPv4 (into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a fundamental interoperability requirement.
In December 2008, despite marking its 10th anniversary as a Standards Track protocol, IPv6 was only in its infancy in terms of general worldwide deployment A 2008 study by GOOGLE INC. indicated that penetration was still less than one percent of Internet-enabled hosts in any country. IPv6 has been implemented on all major operating systems in use in commercial, business, and home consumer environments
This set of Web pages provides information of Internet Protocol Version 6 (IPv6). IPv6 is sometimes also called the Next Generation Internet Protocol or IPng. IPv6 was recommended by the IPng Area Directors of the Internet Engineering Task Force at the Toronto IETF meeting on July 25, 1994 in RFC 1752, The Recommendation for the IP Next Generation Protocol . The recommendation was approved by the Internet Engineering Steering Group and made a Proposed Standard on November 17, 1994.
The core set of IPv6 protocols were made an IETF Draft Standard on August 10, 1998.
Internet Protocol Version 6 is abbreviated to IPv6 (where the "6" refers to it being assigned version number 6). The previous version of the Internet Protocol is version 4 (referred to as IPv4).
IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. It is a natural increment to IPv4. It can be installed as a normal software upgrade in internet devices and is interoperable with the current IPv4. Its deployment strategy is designed to not have any flag days or other dependencies. IPv6 is designed to run well on high performance networks (e.g. Gigabit Ethernet, OC-12, ATM, etc.) and at the same time still be efficient for low bandwidth networks (e.g. wireless). In addition, it provides a platform for new internet functionality that will be required in the near future.
IPv6 includes a transition mechanism which is designed to allow users to adopt and deploy IPv6 in a highly diffuse fashion and to provide direct interoperability between IPv4 and IPv6 hosts. The transition to a new version of the Internet Protocol must be incremental, with few or no critical interdependencies, if it is to succeed. The IPv6 transition allows the users to upgrade their hosts to IPv6, and the network operators to deploy IPv6 in routers, with very little coordination between the two.
The IPv6 working group is an IETF working group chartered to develop the next generation of the Internet Protocol. The working group was previously named the IP Next Generation Working Group (IPNGWG).
The working group is chaired by Robert Hinden / Nokia and Margaret Wasserman / Windriver. Steve Deering chaired the group previously. The IPv6 working group document editor is Robert Hinden / Nokia
The IPv6 working group represents the culmination of many working groups in the IETF working on the internet routing and addressing problems.
The IPv6 working group has an mailing list and mail archive. Complete instructions on subscribing and unsubscribing to the IPng mailing list, and accessing the mail archive.
The Next Generation Transition working group in the IETF is responsible for designing the mechanisms and procedures to support the transition of the Internet from IPv4 to IPv6. Additional information, including how to subscribe to the ngtrans mailing list, can be found on the ngtrans web page .
