IPv6 is more flexible in using protocols which, are mainly defined as the Request for Comment (RFC) that we discussed in the discussions. Protocols are defined in the RFC, but the name of the protocol will be something like Internet Protocol, Internet Control Message Protocol, Telnet Protocol, and many more. The reason why these Protocols are more flexible in the IPv6 is for one, the IPv6 is a newer technology than the IPv4, and the IPv6 also has more functionality and allows more flexibility in the protocols, whereas the

Abstract: The main motive for the development of IPv6 is to add the advanced and better features for the IPv4.Compared to IPv4 there are many better areas in IPv6 such as addressing, Routing , efficiency ,Quality of service, security and mobility. From past three years we have noticed that the IPv4 address exhaustion took place which lead to the development of the next generation internet protocol IPv6.The main aim of this paper is to discuss the transition changes of IPv4-IPv6 .

In this section, I will introduce IPv6 operating mechanisms such as transition technologies that allow its coexistence with IPv4 or essential protocols like Neighbor Discovery Protocol (NDP) the replacer of Address Resolution Protocol for IPv4. Furthermore in this Section I will focus on security aspects regarding all mentioned mechanisms, protocols or IPv6 features like the new security paradigm that raises with the end of NAT or the reconnaissance “game changer” due to huge address space of IPv6.

With admirable foresight, the Internet Engineering Task Force (IETF) initiated as early as in 1994, the design and development of a suite of protocols and standards now known as Internet Protocol Version 6 (IPv6), as a worthy tool to phase out and supplant IPv4 over the coming years. There is an explosion of sorts in the number and range of IP capable devices that are being released in the market and the usage of these by an increasingly tech savvy global population. The new protocol aims to effectively support the ever-expanding Internet usage and functionality, and also address security concerns.

The Internet Protocol (IP) has some vulnerability that can be exploited to transfer information along the network by being anonymous. Some attempts have been made using IPv4 but now since IPv6 is the new mode of network the challenge is to design it to fit the new trend.

IPv6 uses NDP (Neighbor Discovery Protocol) to find the MAC address. NDP manages interaction between nodes via message exchanges. These messages provide the data necessary for the processes of host auto configuration and packet transmission on a local link. Host auto configuration involves separate tasks of Parameter discovery, address auto configuration and duplicate address detection. Packet discovery is facilitated through router discovery process. It obtains the necessary parameters required for host configuration. Duplicate address detection is used to detect the presence of duplicate addresses on the same link. Packet transmission process requires data which can be obtained by router discovery, prefix discovery, address resolution, neighbor

IPv6 is not a solution for security, however, in light of the fact that few security issues

The world of technology is dynamic. Technology has been revolutionized to its current status of industry four. This has seen various changes in the information technology, in the previous time the Internet Protocol 4 (IPV 4) was used to identify the IP address. Times have changes leading to the development of IPV 6 which can handle multiple addresses at a time. The IPV 6 handles 3.4 x 1038 addresses at a single time. This recommendable since the world has evolved to use of digital systems that require IP addresses every time. This paper explains the effects of technology developments, benefits and the flaws involved. The development of technology has been used in various industrial fields that include, industrial production, aquatic study, and research, smart lighting among others.

to the continued growth of the Internet. IPv6 was first known as the Next Generation

The need for IPv6 is growing by the day. There are good amount of reasons why the migration of IPv6 is not only desirable, but necessary in days to come. Some of the areas were IPv6 benefit from are reduced address space, advanced security features, enhanced quality of service, and stateless auto configuration. (IPv6 and the Future of the Internet).

Efficient and hierarchical addressing and routing infrastructure - IPv6 global addresses that are used on the IPv6 portion of the Internet are designed to create an efficient, hierarchical, and summarizable routing infrastructure that is based on the common occurrence of multiple levels of Internet service providers.

With technology continually progressing and the volume of people that use the Internet increases, the amount of IP addresses are shrinking. IPv4 addresses were though of prior to the Ipv6 technology and are more common among households an and business. However, the IPv4 addresses are slowly depleting from the world. What already occurred in Europe, and what is currently happening in North America is the extinction of IPv4 addresses. To solve this problem users are starting to move into using IPv6 addresses.

IPv6 are better security, since the security for IPSEC is built into IPv6 upgrade; more available IP address, since we are switching from a 32 bit system to a 128 bit protocol; IP address can be close to an unlimited number and should not run out, but as with IPv4, it could happen; better and faster service for video screaming, games, and video conferencing since the UDP will work much better for screaming of video quality of services; and an auto configuration of all router on the system and it has a larger

IPv6 is the latest version of internetworking protocol designed to answer all the limitations of the current standard Internet Protocol IPv4. Transitioning to the next generation of Internet Protocol became an issue with the mass standardisation of IPv4 since the early start of Internet. And due to the fact that IPv4 and IPv6 are incompatible with each other. Therefore, a transition mechanism is required during the migration from IPv4 to IPv6 networks.

The migration to IPv6 has started already, but it is still in its early stages. The current IPv4-based Internet is so large and so complex that the migration from IPv4 to IPv6 is not as easy as the transition from NCP network to TCP/IP in 1983. One of the most important concepts that should be deliberately weighed is, How to protect the investment that already exists and reduce the negative influence on users and ISPs during the transition process. Certainly, the research on IPv6 transition is of vital importance for the success of IPv6 protocol and the future of the Internet.
