Addresses are one of the most useful inventions of the past. They are used to locate somebody or something spatially or geographically, to identify a fixed or mobile device or to send messages to electronic mailboxes. Most of these addresses have a textual representation being easy to remember or they may consist of numbers easy to forget -therefore the phonebook was invented. In case of electronic communication, no user needs to care much about the decimal or hexadecimal representation of addresses being used by technical systems to connect to each other or to send messages around. We are used to writing names such as www.ec.europa.eu to address a server instead. Yet, basically all communication between all stakeholders takes place based on IP addresses. This booklet will give a short introduction to IP addressing and the structure of IPv6 addresses, on how you can get IPv6 address space and the options you have to structure and tailor the address space to your needs. The German address plan will be used as an example.

This article presents a proposal for a guide to best practices to support Information Technology [IT] areas in the planning and implementation of the transition of their infrastructure and technology services to IPv6 protocol. For this purpose an analysis of references was done to identify the problem, comprehend the state of the art; the current state of advance in the migration to IPv6 and its implementation worldwide; the state of the art of technology in the regions where it is a key factor and the process that these regions have developed to explore and implement the transition from IPv4 to IPv6, and as an analysis of the manner in which their governments assumed this transition; the identification of how the processes of the model of best practices for IT, ITIL v.3 can support the transition; and the existing mechanisms of technological transition from IPv4 to IPv6 according to two scenarios: with and without IPv4 and IPv6 coexisting. ; Este artículo presenta una propuesta de guía de buenas prácticas para asistir a las áreas de Tecnología de la In-formación [TI] en los procesos de planeación e implementación de la transición de sus servicios de infraestructura y tecnología hacia el protocolo IPv6. Se realizó un análisis de referencias para la identificación del problema y un exhaustivo estudio del estado del arte, particularmente se puntualizó en el estado actual del avance en la migración hacia IPv6 y su implementación a nivel global, en el estado actual de la tecnología en las regiones donde este protocolo es un factor clave y en el proceso que esas regiones han desarrollado para la materialización de la transición. Tam-bién se presentan los resultados del análisis de los métodos lleva-dos a cabo por los gobiernos para materializar dicha transición, la identificación de cómo los procesos del modelo de buenas prácticas para TI de ITIL® pueden soportar esta transición y los mecanismos existentes de transición tecnológica de IPv4 a IPv6 bajo dos escenarios: con y sin coexistencia de ambos protocolos.

International Journal of Advanced Computer Science and Applications(IJACSA), 7(9), 2016 ; IPv6 is being the new replacement for its predecessor IPv4, IPv6 has been used by most Internet services and adopted by most internet architecture these days. Existing protocol IPv4 reveals critical issues such as approaching exhaustion of its address space, continuous growth of the internet and rising new technologies lead to increasing the complexity of the configuration, etc. To healing from the limitations of IPv4 Internet Engineering Task Force (IETF) developed the next generation IP called IPv6. Jordan, like many other countries, is endeavoring to adapt and transit from IPv4 to in an efficient way that will provide an excellent level of service as coveted by its citizens. In this study, the author tried to navigate IPv6 concept from the literature and review the thoughts, steps, and challenges that the Jordanian government pursued in transiting from IPv4 to IPv6. ; http://thesai.org/Downloads/Volume7No9/Paper_36-Between_Transition_from_IPv4_and_IPv6_Adaption.pdf

El inminente agotamiento de las direcciones de IPv4 generó el desarrollo del protocolo de Internet versión 6 (IPv6). Este protocolo provee una mayor cantidad de direcciones IP, además de incluir mejoras del protocolo IPv4. Es necesaria la adopción del IPv6 por las distintas entidades e instituciones alrededor del mundo para así lograr una convergencia a nivel de protocolo. Con esto se dispondría de una gran cantidad de direcciones IP que permitirán dar paso al desarrollo de nuevas tecnologías de vanguardia. Este trabajo consiste en un Plan de Acción conformado por tres fases, el mismo que tiene como principal objetivo implementar IPv6 en el Ecuador. Entre algunos de los criterios utilizados para el desarrollo del Plan de Acción en mención, han sido las diversas estrategias adoptadas por los países que actualmente cuentan con IPv6, así como las políticas emitidas en torno a IPv6 por instituciones internacionales y nacionales. Una inmediata adopción del protocolo IPv6 permitiría el crecimiento tanto tecnológico como económico en los distintos sectores como el Gobierno, la Industria, la Academia y la Sociedad Civil en general. ; The depletion of the IPv4 addresses led the development and deployment of the Internet protocol version 6 (IPv6). This protocol provides a greater number of IP addresses and includes improvements to the IPv4 protocol. It is very important for the different agencies and companies all around the world to start the adoption of IPv6 in order to achieve a protocol level convergence. In consequence there will be a large number of IP addresses that will give way to the development of new cutting-edge technologies. This article consists of an Action Plan made up of three phases which main objective is to guide the deployment of IPv6 in Ecuador. Some of the criteria used for the development of this Action Plan was various of the strategies adopted by countries that currently have IPv6, as well as policies regarding IPv6 issued by international and national institutions. An immediate adoption of IPv6 would allow both technological and economic growth in many sectors such as Government, Industry, Academy and Civil Society.

Sieht man von der Erweiterung des Adressraums ab, so bietet das neue Internet-Protokoll IPv6 gegenüber seinem Vorgänger IPv4 nichts revolutionär Neues. Einiges wurde aus IPv4 übernommen, einiges verbessert, einiges, was bereits für IPv4 angedacht war, wird nun implementiert. Für einige neue Leistungen, wie die Dienstgüte für Multimediaanwendungen, sind zwar Protokollelemente definiert, jedoch fehlt noch eine verbindliche Interpretation der Elemente und die Verpflichtung, diese zu berücksichtigen. Größere Probleme werden wohl die konkret implementierbaren Sicherheitsmechanismen machen. IPv6 wird IPv4 nicht sofort ablösen, vielmehr werden beide Protokolle über Jahre nebeneinander existieren. Angesichts der Tatsache, daß beide Systeme nicht kompatibel sind, werden sich aus diesem Nebeneinander viele Probleme ergeben. Da die Umstellung auf IPv6 für die Anwender mit erheblichen Kosten verbunden ist, wird dieser Prozess recht lange Zeit in Anspruch nehmen. (KB)

In today's generation, most of today's Internet is using IPv4, Now twenty years old. IPv4 is now uploading with the Problem of meeting growing Internet requirements and it is a shortage of IPv4 addresses, which are necessary for all new the machines added to the Internet.IPv6, fixes a series of problems In IPv4 addresses. It also adds many improvements to IPv4 and provides a better network. IPv6 is expected to gradually replace IPv4, with the two coexisting for several years during a transition period. As the population is increasing day by day, similarly the Internet isAlso growing and expanding more and more and more and more,Government, scientists and universities are looking for new waysTo send information quickly and powerfully The two new InternetsDevelop new and faster technologies to improve research andCommunication, and both projects are expected toEventually improve the current commercial Internet. A big advantage of IPv6 is that it simplifies and solves the problem. The scarcity of IP addresses. In today's Internet technology, Controls in the United States 74% of the 4 million IP addresses, while the amount that China has is equal only to the University California, but its share of 80 million users. This is the main reason Asian countries, especially China, Japan and South Korea, Show interest in IPv6 version technology.

IPv6 provides more address space, improved address design, and greater security than IPv4. Different transition mechanisms can be used to migrate from IPv4 to IPv6 which includes dual stack networks, tunnels and translation technologies. Within all of this, network security is an essential element and therefore requires special attention. This paper analyses two transition technologies which are dual stack and tunnel. Both technologies are implemented using Cisco Packet Tracer and GNS3. This work will also analyse the security issues of IPv6 to outline the most common vulnerabilities and security issues during the transition. Finally, the authors will design and implement the dual stack, automatic and manual tunnelling transition mechanisms using Riverbed Modeler simulation tool to analyse the performance and compare with the native IPv4 and IPv6 networks.
