The Transition Of Internet Through Ipv4 Ipv6

The IPv4 came before the IPv6 and these datagrams are similar in many ways but also differ in more ways than one. IPv6 came out in the year 2004 and still uses many of the features that made IPv4 so successful. IPv6 is supposed to become the new standard over the older version of IPv6, but it is tough for v6 to take its spot when v6 cannot support everything v4 does, basically v6 cannot connect to a v4 system. Some differences are that it is stated that the IPv6 is more secure than the IPv4, the address size went from 32 bits in the IPv4 to 128 bits in the IPv6, extensible protocols are more flexible in the IPv6, IPv4 and IPv6 are not compatible, the IPv4 will not be able to support additional nodes or support for applications, and the

With the rapid growth of the Internet after commercialization in the 1990s, it became evident that far more addresses than the IPv4 address space has available were necessary to connect new devices in the future. By 1998, the Internet Engineering Task Force (IETF) had formalized the successor protocol. IPv6 uses a 128-bit address, allowing 2128, or approximately 3.4×1038 addresses, or more than 7.9×1028 times as many as IPv4, which uses 32-bit addresses and provides approximately 4.3 billion addresses. The two protocols are not designed to beinteroperable, complicating the transition to IPv6. However, several IPv6 transition mechanisms have been devised to permit communication between IPv4 and 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 is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

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

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.

One area were IPv6 trumps IPv4 is address space. IPv4 is a 32 bit address and provides about 4.3 billion internet addresses. IPv6 is 128 bit address and provides about 340 trillion internet addresses. Since the earth is around 7 billion in population, IPv4 is no longer enough for all the devices on earth. Because of IPv4 limitations, the implementation of IPv6 became more of a necessity. This abundant number of IPv6 addresses makes it more than enough for every person on earth to have billions of addresses for every device they own. (Infographic: IPv4 vs IPv6).

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.

IP6 as a protocol has not been universally adopted yet, but it will be, and by that time many early adopters will have switched to whatever is better and newer. All of this, including the possibly trillions of tiny nodes on line from connected devices will function because Internet routers and packet switchers are now capable of sorting traffic by type and size. So although traffic will increase capacity will increase alongside it (Schwartz 8-8). The world is imagined as totally connected with a monumental network of interactive devices to control everything from our home systems and appliances to parking meters and car systems ("App Central.").Tech companies are looking to sell more devices. Other companies want to ride the wave of profit and customers simply want all the new gadgetry to make life easier, or at least more interesting.

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

The internet matured in the 1970's as a result of the Transmission Control Protocol/Internet Protocol (TCP/IP), which is sill used today. It was adopted by the U.S. Department of Defense in 1980, and universally adopted in 1983. The usage of TCP/IP is what unites all elements of the net. Both public domain and commercial implementations of the roughly one hundred protocols of the TCP/IP protocol suite became available in the 1980's. During the early 1990's, Open Systems Interconnection (OSI) protocol implementations also became available by the end of 1991, the Internet has grown to include some 5,000 networks in over three dozen countries, serving over 700,000 host computers used be over 4,000,000 people. By December 1996, about 627,000 Internet domain names had been registered and now there are more than 30 million registered.

Well, I can assure you that mysterious people, in lab coats and bright lit computer labs are hard at work trying to come up with the next version of IP. What do you think it will be? IPv7? IPv9? I am not sure, but I am excited to find out.

A big yes to IPV6 ,This report will explain my reasoning why I had chosen yes for IPv6 in detail

This video was really compelling and includes a lot of aspects that sometimes we as parents forget that real threats are there. As a computer science mayor and with an experience of twenty years plus I can say that the internet indeed grows at exponential rates every month. In an article published by (TechnoLlama, 2009) “In countries like the UK, ISPs are struggling to keep up with growing bandwidth demands from online gamers, P2P, Web 2.0 sites, and streaming services such as Last FM, BBC’s iPlayer, and Spotify.” And that was in 2009, in 2012 IPv6 protocol went live. The reason is that this is the next generation of what we knew as IP (IPv4) and “IPv4 has only 4.3 billion addresses, and with PCs, smartphones, tablets, gaming systems, and just about everything else connecting to the Internet we've tapped the system dry. IPv6 uses 128-bit addresses and is capable of 340 undecillion addresses. That is 340 times 10 to the 36th power, or 340 trillion trillion trillion possible IP addresses” (Bradley, 2012).

Since there are so many IP addresses that need to be handled on the Internet, IPv4 and IPv6 need a way to keep track and configure them. This is normally referred to as address resolution. This includes translating network layer addresses into link layer addresses, having automatic assignments of addresses, and routing data to the correct location on a specific network. IPv4 uses a protocol called Address Resolution Protocol, or ARP, in order to translate IP addresses into MAC addresses. A MAC address is the unique number given to the network interface card in each computing device. The reason this needs to be done is because on many intranet networks, the internal communication and delivery of data is based off of the MAC address rather than the IP address. The Dynamic Host Control Protocol, or DHCP, handles the automatic configuration and assignment of IP addresses in IPv4. DHCP is an internal protocol that takes the MAC addresses of the NICs on a network, and automatically assigns IP addresses. It also keeps track of them so that two NICs don’t acquire the same IP address. Without DHCP every IP address would have to be entered manually by the system administrator, which would be incredibly difficult considering how many devices can potentially access a network. IPv6 uses similar methods to perform both of those functions, but there are still important differences that exist to improve the way that IPv6 performs. Instead of ARP, IPv6 uses the Neighbor Discovery Protocol
