IPv6

(Internet Protocol Version 6) The latest generation of the IP protocol. The specification was completed in 1997 by the Internet Engineering Task Force (IETF) and first deployed in 2004 when ICANN added IPv6 records to its DNS root servers for Japan and Korea. IPv6 is backward compatible with IPv4 and was designed to fix its shortcomings, such as data security and maximum number of user addresses.

Virtually Unlimited Devices
IPv6 increases the address space from 32 to 128 bits, providing for all practical purposes an unlimited number of unique addresses for connection to the Internet (see Internet of Things and binary values). It also supports quality of service (QoS) parameters for real-time audio and video. Originally called "IP Next Generation" (IPng), IPv6 and IPv4 exist side-by-side.

What Happened to IP Version 5?
IPv5 was an experimental streaming protocol that was not involved with IP address space. See 6LoWPAN, IPv4 address exhaustion and IP address.
