-[Acronym] for InternetProtocol version 6.
+!!!The Great Big WLUG Guide to IPv6
-Sometimes called IPng.
+!!What is IPv6?
-IPv6 has more addresses and funky new features such as different address scopes
(LinkLocal
,SiteLocal
,GlobalScope)
, AnyCast
, and MultiCast (and no more BroadCast), unfortunately no
one supports it yet

+IPv6 is an [Acronym] for Version 6 of the InternetProtocol. It is the next version from [IPv4]
(technically
, IPv4 was the first production version. To paraphrase
, to pick the replacement
, there were four versions proposed
, numbered 5 -> 8; 6 was the
one that they picked
.)
It is sometimes known as IPng
.

+!!Why do I want to
use it?
-IPv6 is the next version from [
IPv4]
.
+IPv4, with it's 32 bit address space, has 2^32 addresses (4,294,967,296). While that sounds like a lot, remember that there are more people than that on the planet, and various allocation decisions seriously cut down the usefulness of those 4 billion addresses (for example, 1/256 of the space, 127/8, is reserved to refer to "My Local Machine"! 16
.7 __million__ addresses for localhost!)
-See [IPv6Addressing]
+IPv6 has more addresses. How many?
-Does anyone know if any NewZealand [ISP]s have support for ipv6 (from customer's point of view)?
+!!340,282,366,920,938,463,463,374,607,431,768,211,456.
-See our
[IPv6LessonsLearnt
] for some general hints about random things we've learnt while playing with [IPv6]
+That’s more than 665,000,000,000,000,000,000,000 addresses per surface square metre on Earth. So, if you want your toaster to have a large block of IP addresses, you can!
See [IPv6Addressing
] for some information.

also [IPv6Setup

[6to4
].

+
+!!Getting IPv6
+
+There are three methods; get a native allocation of IPv6 addresses from your Internet provider (uncommon; especially in New Zealand), get a tunnel from a tunnel broker, or use IPv6's built IPv4 compatibility. See [IPv6Setup] and [6to4].
+
+!!IPv6 in the DNS
+
+The average IPv6 address is represented as something like "fedc:ba98:7654:3210:fedc:ba98:7654:3210". If you know a couple of IPv4 addresses off the top of your head, you will really want to think about making [DNS] work for you come IPv6 deployment! Thankfully [DNS] supports IPv6 addresses; there are two types of record, [AAAA] and [A6]. See [AAAAvsA6] for details about the differences.
-For information about [AAAA] and [A6] [DNS] records, see [AAAAvsA6]
