IPv6 addresses are 128 bits long as opposed to the 32 bits used by the current IPv4 addresses. The main benefit of this is that it provides __LOTS__ more addresses.
Some common prefixes:
+* ::_aabb_:_ccdd_ -- Used for IPv4 addresses (_a.b.c.d_) (obsolete)
+* ::FFFF:_aabb_:_ccdd_ -- Used for IPv4 addresses (_a.b.c.d_) as per RFC:4038
+* 2000::/3 -- addresses with GlobalScope, as allocated [here|http://www.iana.org/assignments/ipv6-unicast-address-assignments/] (older version [here|http://www.iana.org/assignments/ipv6-tla-assignments])
* 3FFE:831F::/32 -- This is used by [Teredo]
-* 2002
::/16
-- This is used by
[6to4

+* FC00
::/7
-- [ULA

* FE80::/64 -- LinkLocal
-* FEC0::/48 -- SiteLocal
-* ::FFFF:aabb:ccdd -- Used for IPv4 addresses
(a.b.c.d
)
+* FEC0::/48 -- SiteLocal (deprecated
)
+Subsets of 2000::/3 space:
+* 2001:DB8::/32 -- reserved for example addresses in documentation as per RFC:3849
+* 2002::/16 -- This is used by [6to4]
!!Notation
The preferred form for writing IPv6 addresses is x:x:x:x:x:x:x:x where each x represents the hexadecimal values of 16 bits of the address. Examples:

There is no broadcast addresses, as these have been replaced by multicast ones.
