Abstract

IPv6 (Internet Protocol Version 6) is one of the most important protocols of the Advanced Internet. The current IPv4 used in Internet 1 presents several limitations such as limited addressing capacity, no native support of QoS (Quality of Service) parameters and lack of security. This presentation discusses the drawbacks of the current IPv4 and describes how these problems are solved by IPv6, introducing its main features related to addressing, routing, QoS capabilities, security and mobility. Transition strategies from IPv4 networks to IPv6 networks are also presented and discussed taking as basis some study cases.
