Internet Protocol Version 6 (IPv6) is an Internet Protocol (IP) used for carrying data in packets from a source to a destination over various networks. IPv6 is the enhanced version of IPv4 and can support very large numbers of nodes as compared to IPv4. It allows for 2128 possible node, or address, combinations.
IPv6 is also known as Internet Protocol Next Generation (IPng).
Released June 6, 2012, IPv6 was developed in hexadecimal format and contains 8 octets to provide large scalability. Like IPv4, IPv6 deals with address broadcasting without containing broadcast addresses in any class.
