In 1993, IETF formed the Internet Protocol Next Generation (IPng) Group to evaluate the proposals and it will be responsible in determining how to proceed in selecting a successor to the IPv4.IPng evaluated and reviewed the proposals of [[CATNIP]],[[SIPP]] and [[TUBA]]. After numerous discussion the IPng Directorate recommended the adoption '''Simple Internet Protocol Plus (SIPP) Spec. (128 bit version)''' as the basis for the next generation of Internet Protocol. The version number 6 was assigned by IANA and it was officially called IPv6.<ref>[http://datatracker.ietf.org/doc/rfc1752/?include_text=1 RFC 1752]</ref>

==IPv6 Working Group==
 +
The IPv6 Working Group was created by the IESG as the IP Next Generation ([[IPng]]) working group to implement the recommendations of the IPng Area Directors set forth during the IETF meeting on July 1994 as described in RFC 1752 entitled, The Recommendation for the IP Next Generation Protocol. The IPv6 working group's primary role is to oversee the specification and standardization of IPv6.<ref>[http://datatracker.ietf.org/wg/ipv6/charter/ IP Version 6 Working Group]</ref>

The IPv6 Working Group was created by the IESG as the IP Next Generation ([[IPng]]) working group to implement the recommendations of the IPng Area Directors set forth during the IETF meeting on July 1994 as described in RFC 1752 entitled, The Recommendation for the IP Next Generation Protocol.

An IPv6 address is written in hexadecimal quartets separated by colon for example: 2001:cdba:1900:0000:0000:0000:1757:3618 If there is a four-digit group of zeroes within an IPv6 address, it can be reduced to a single zero and delete the group of 4 zeroes and the address can be written as:2011:cdba:1900:0:0:0:1757:3818 or 2001:cdba:1900:3257:9652<ref>[http://ipv6.com/articles/general/IPv6-Addressing.htm IPv6 Address Notation]</ref>

 +
==Types of IPv6 Addresses==
 +
IPv6 has three types of addresses which include a '''Unicast address''', which serves as a single interface identifier and it is delivered to the interface identified by the address; '''Multicast Address''', an identifier for a group/set of interfaces that may belong to the different nodes delivered to multiple interfaces and the '''Anycast addresses''', an identifiers for a set of interfaces that may belong to different nodes and it is delivered to any of the interfaces identified by the address.<ref>[http://ip6.com/articles/general/IPv6-Addressing.htm Types of IPv6 Address]</ref>
 +
 
 +
==IPv6 Special Addresses==
 +
The next generation Internet Protocol version 6 has special address which include:<ref>[http://ipv6.com/articles/general/IPv6-Addressing.htm IPv6 Special Addresses]</ref>
 +
# ::/96 The zero prefix denotes addresses that are compatible with the previously used IPv4 protocol.
 +
# ::/128 An IPv6 address with all zeroes in it is referred to as an unspecified address and is used for addressing purposes within a software.
 +
# ::1/128 referred as loop back address and is used to refer to the local host. An application sending a packet to this address will get the packet back after it is looped back by the IPv6 stack. The local host address in the IPv4 was �127.0.0.1�.
 +
# 2001:db8::/32 This is the official documentation prefix  allowed by IPv6 which denotes that the address is only an example
 +
# fec0::/10 is a site-local prefix offered by IPv6 which implies that the address is valid only within the local organization.The use of this prefix is discouraged by RFC
 +
# fc00::/7 referred as the Unique Local Address (ULA) which are routed only within a set of cooperating sites. It was introduced to replace the site-local addresses and provides a 40-bit pseudorandom number which lessens the risk of address conflicts.
 +
# ff00::/8 is a prefix used to automatically denote a multicast addresse
 +
# fe80::/10 is a link-local prefix offered by IPv6 signifying that the address is valid only in the local physical link.
