Hi, need to submit a 2000 words essay on the topic Compare and Contrast between IPv4 and IPv6. Why IPv6 Hasn't Been Implemented on the Internet.

It delivers datagrams or packets from the source to the destination host by only basing on their addresses. Over the years, the IP has undergone revisions in its development and the Internet Protocol version 4 (IPv4) is its 4th revision. Another recent revision is the Internet Protocol version 6 (IPv6). Both IPv4 and IPv6 are at the core of internet internetworking methods that are standards-based. However, there exist differences between the two versions of the IP as well as their levels of deployment. Since its development, the IPv4 is the first version of the internet protocol to be widely deployed and until today, it is still stands out as the Internet Layer protocol that is widely deployed. This is so despite the development of more advanced version of the IP, the IPv6. This is an indication that there is something about the IPv4 that makes it more popular than the IPv6. I choose this topic with an aim of knowing the differences and similarities that exist between the IPv4 and IPv6 so as to identify why IPv6 has not been implemented on the internet. ...

From these, it is expected that IPv6 should have achieved a greater level of deployment than the IPv4. But as it is, the deployment of IPv6 is still at its infancy. This paper analyses the reasons as to why IPv6 has not been implemented on the internet. Literature Review In order to identify the reasons as to why IPv6 has not been implemented on the internet, it is important to understand the similarities and differences between IPv4 and IPv6. This will be important in identifying any weaknesses that underlie the IPv6 and provide a base for making recommendations for improvements that will enable it to achieve a good level of deployment. For this paper, the sources of the literature review and analysis will be books, journals and articles on computer sciences and information technology. credible online sources on the same will also be used. Similarities Both IPv4 and IPv6 are internal layer protocols designed for packet-switched internetworking. The two IP versions are also capable of providing end-to-end datagram or packet transmission across more than one IP networks. In terms of the structure of their packets, both the headers of IPv4 and IPv6 have an optional fields or extension that can be used to implement special features. Differences According to (Shankland, 2011), IPv4 allows 32 bits for an IP and because of this, it can support 232 (4,294,967,296) addresses. On the other hand, IPv6 uses 128-bit addresses, therefore, the developed address space supports 2128. This is about 340 undecillion or 3.4?1038 addresses. This makes the large address space an important feature of IPv6 over IPv4. This expansion creates room for more devices and users on the internet.
