Abstract
IPv6 is short for "Internet Protocol Version 6". IPv6 is the "next generation" protocol designed by the IETF (The Internet Engineering Task Force) to replace the current version Internet Protocol, IP Version 4 ("IPv4"). The IP v 6 specifications are in RFC- 2460. Most of today's Internet uses IPv4, which is now nearly twenty years old. IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems. Most importantly, there is a growing shortage of IPv4 addresses, which are needed by all new machines added to the Internet. IPv6 fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network auto configuration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period.

Internet Protocol Version 6
[attachment=18272]
ABSTRACT
The paper discusses on the up coming trends and the technologies used in the Internet World. It will explore the topic on IPV6 i.e. Internet Protocol Version 6.
We say Internet Protocol Version 6 but what is this Protocol stuff; get familiarized with what is Protocols first and then we start with the in-depth study of IPV6. Like its previous versions IPV6 is all set to make waves in the Internet World. Here we will see what IPV6 is, why IPV6 is selected and why we need IPV6.The paper justifies what are the problems of the current IP we are using and how it is wearing out with time and increase in number of users.
In addition this will explore a bit of the history of the Internet Protocols and the forums, which are anticipating and sparing their attentions to these development. It covers the description of all the rules used for the addressing methods in Ipv6. Included here is also the compatibility of the Ipv4 address with that of Ipv6. How an Ipv6 address can be converted in to the present Ipv4 address to identify the node is also covered.
This will give a brief idea on some of the key features of IPV6 where it discusses IPV6 as a re-engineering effort against IP technology. Features includes firstly Larger IP address and it use for end-to-end communication. Deploy more technologies the future prospects and covers within it Auto Configuration describes and stateless host like mandatory facilities, Security tells about this mandatory feature, friendliness to traffic technologies describes about the compatibleness of Ipv6 with future technologies. Then it continues with multicast becoming mandatory, better support to ad-hoc feature facilitating anycast, it also a cure to routing tables, it specifies the simpler header structure, allows flexible protocol extensions which provides hardware acceleration, smooth transition form Ipv4 showing its compatibility with Ipv4, follows key design principles of Ipv4 justifies its proper structure.
INTRODUCTION:
What is a Protocol? What is this stuff? Well, a Protocol is a set of rules, which is used for connecting some computers in a network. As for example a man goes to some different land and want to find his destination. Then there should be some standard pattern for such people to talk to each other or to communicate. These standard patterns are some set of rules with which you need to send your data to this distant land and talk to the person. Thus there is standard set of Protocols without which our communication is impossible for the Network Of Networks or INTERNET. These Protocols are thus called INTERNET PROTOCOLS.
At the end of 2002, an international team from California and the Netherlands sent 6.7 gigabytes of data across 6,821 miles of fiber-optic network in less than one minute. That's roughly two full-length DVD-quality movies traveling a quarter of the way around the Earth at an average speed of 923 megabits per second. Believe me that's fast.
WHAT’S IPV6?
IPv6 is short for "Internet Protocol Version 6". IPv6 is the "next generation" protocol designed by the IETF to replace the current version Internet Protocol, IP Version 4 ("IPv4").
Most of today's Internet uses IPv4, which is now nearly twenty years old. IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems. Most importantly, there is a growing shortage of IPv4 addresses, which are needed by all new machines added to the Internet.
IPv6 fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network auto configuration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period.
Some introductory information about the protocol can be found in our IPv6 FAQ. For those interested in the technical details, we have a list of IPv6 related specifications.
1.2.) WHY IPV6?
It is a problem that these features are optional for IPv4, and it is very important to include features of IPv6 into the basic spec. If you don't see why, imagine the following story: You are very novice user of the Internet, who can hardly do if config or routing setup. You carry along your laptop, and visited some university for presentation. Just after you connected your laptop to the local network, the chairman said that there is no DHCP server available in the university, and administrator took a day-off.
1.3.) WHY DO I NEED IPV6?
It is not a matter of if, but when, IPv4 address space will run out. Address re-use is a short-term solution that restricts facilities. Scarcity of IP addresses will lead to rationing, either by arbitrary control, or by price. With IP Version 6 (IPv6) [also sometimes referred to as Ipng] there will be no scarcity of addresses.
Address re-use mechanisms work for people who just use e-mail and the Web, but it is not viable for servers, which need dedicated IP addresses.
