Técnicas de transição para IPv6

Abstract

For computers communication in the Internet is needed to use IP address (Internet Protocol). Currently the Internet use IPv4 (Internet Protocol Version 4). IPv4 address exhaustion in the world happened since February 2011, when the distribution of the last remaining of IPv4 address blocks to each regional organization assignments, informed by IANA (Internet Assined Number Authority), and exponential growth of the Internet and all kinds of devices connected to it, happens the rapid depletion of the last remaining IPv4 addresses. In order to propose an alternative to the impending end of IPv4, IPv6 (Internet Protocol Version 6) was developed, that allows the creation of an infinitely larger number of public Internet addresses. This paper aims to describe the features and functionality of the IPv6 protocol as well as techniques for the transition from IPv4 to IPv6 will be extremely important to businesses, educational institutions and Internet service providers. This work also aims to technicians, engineers, systems analysts who will use this document as a basis for studies and projects that will be needed for the use of IPv6 in their fields. It is shown also the current scenario of IPv4 and IPv6 in Brazil and the world and a case of study.
