What is IPv6?
IPv6 appeared as a protocol designed to overcome some of the inherent issues in IPv4. Since the protocol was developed taking into account improvements needed for IPv4, such as security, one could think that IPv6 and its new set of features are a glass of water for someone in the middle of desert. IPv6 include several security improvement next to IPv4. IPsec, for example, is a gold star that creates expectations regarding embedded privacy, authentication, and authorization. The possibility of having encrypted communications over almost any network is as promising as the idea of having enough IP addresses available not to have to worry about VLSM anymore.
