IPv6
IPv6, short for Internet Protocol version 6, and sometimes referred to as IP next generation, is a network protocol for Internet and Ethernet network transmission and replaces the earlier IPv4. IPv6 includes improvements over IPv4 such as a wider range of Internet addresses, improved routing and autoconfiguration, embedded encryption, and more. Not all operating systems and applications are able to utilize IPv6; however, new software is slowly making the transition to it.Also see: IPv4, Network definitions, Protocol
