Ipv4 to Ipv6 Transition

The reason why the address is longer in v6 is because it can support over 340 undecillion IP addresses. Mainly because the IPv6 has potential to have problems just like the IPv4 address problems. Also, the IPv6 has been broken down into geographical locations, meaning that the address can be tracked to a specific location in the world. The downfall in this part, in my opinion, in a hacker’s point of view, is that you can breakdown a specific location where you would want to attack, if you know the geographic location of the hexadecimal in the address. What I mean is that you can know the country code in the IPv6 address and focus your attack in that specific location. Having a random order of the v6 address would make it more reliable and more secure but also would allow disorder, not knowing where specific address might be located.

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 .

During the last decade, most people simple thought something like “I am just running IPv4 and it works well... so I don´t care about IPv6 yet!”.

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

IPv4 address exhaustion- A term referring to the very real problem in the worldwide Internet, which first presented itself in the late 1980s, in which the world appeared to be running out of the available IPv4 address space.

Over the course of the next twenty years it was mainly utilized by the United States military and government to communicate with each other during the “cold war” with the Soviet Union, and the allies of the United States. By 1982 the concept and use of the Internet had been reshaped by the Internet Protocol Suite (IPS). (CNN.org) The idea eventually evolved and was adapted by the United States in 1986, when the Internet Protocol Suite expanded and began to provide access to supercomputer sites for research and educational organizations. The internet further evolved by the mid-1990’s into the mass commercial use we see today, with many early use restrictions lifted. Since then the Internet has continued to expand and continues to advance. (Wikipedia.org)

AnswerB is incorrect because an IPv4 address is a 32-bit address consisting of four 8-bitoctets, each octet ranging from

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).

Since its advent the Internet has been making its way into very farfetched corners of the world, allowing people to virtually reduce distances. Now the Internet was based on a notion called IP (Internet Protocol), Internet Protocol Version 4 (IPv4) to be exact. Now as the number of computer connected to the Internet grows, the amount of numbers in the IPv4 protocol was finite. Simply put, there are 2^32 useful addresses in IPv4 (subtracting the loopback and the non-routable). With all the connected computers (and growing) this number looks very small. That being said the number of non-allocated IPs is decreasing at a very fast pace. To cater to this problem IPv6 is brought forward. Although there are a lot of problems with the implementation, it certainly brings forward a huge pool of addresses supplemented by some really good security benefits. Some of them include decreased vulnerability to the man in the middle attacks and larger atmosphere surface area, making worm proliferation less effectual. While some may consider these benefits to be negligible, they should be embraced within a set economic cost.

Better support for quality of service (QoS) - IPv6 provides better quality of services because new fields in the IPv6 header define how traffic is handled and identified.

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.

Tout de suite there are two versions of Internet Protocols on the web. The predominant version is IPv4 and a leading-edge advanced version which is called IPv6. The IPv6 is an evolutionary enhancement to the Internet

IPv4 addressing is the next method, it’s is split up into two main parts as well Network I.D and Host I.D which are split over four octets which are written as four decimal numbers which have 32 bits, it only contains 4.3billion different IPs. For example, you sent an IP to a website and it sends its IP back, which means you can communicate. Whereas IPv6 addressing has 128 bits and is written as

IPv6 stands for Internet Protocol version 6. This protocol has been designed to replace the existing Internet Protocol version 4 (IPv4). (01033069). For more than twenty years, IPv4 has been widely used in Internet activities around the world. The main reason for the deployment of a new version IP is to increase the address space. IPv6 was designed to take an evolutionary step from IPv4. According to experts in the field of computer network, over the next five to ten years, IPv6 will gradually integrate into the existing IPv4
