==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.

* '''::/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.

* '''::/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.

* '''::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

* '''2001:db8::/32''' 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

* '''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.

* '''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

* '''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.

* '''fe80::/10''' is a link-local prefix offered by IPv6 signifying that the address is valid only in the local physical link.
