Let's dive into the changes caused by IPv6

body:

So we had all those nice, theoretical articles about
how IPv6 **could** change the future. At ungleich we are already
seeing many things changing and for that reason we start this series
of blog articles about how IPv6 changes the world.

## The Base Claims

When starting a series of blog entries about how IPv6 changes the
world, there are some assumptions and general understandings. In this
article we will try to illustrate what we think is already given.

## Claim 1: Everyone can have IPv6 connectivity

We know that not every ISP provides IPv6 connectivity yet, but that
is really not a show stopper for IPv6 connectivity. We have even
written an [blog article about how to get
IPv6](https://ungleich.ch/en-us/cms/blog/2019/02/05/how-to-get-ipv6/)
and our conclusion is: **everyone can have IPv6 connectivity**.

If you are missing options there, give us a shout, we are glad to
add them. Point being, we are very confident saying there is nobody
who cannot have IPv6 connectivity anymore. We even offer
[free IPv6 connectivity to hacker spaces](https://ungleich.ch/u/blog/free-ipv6-vpn-for-hackerspaces/).

If you very much disagree with us, we are open to be challenged by you.

## Claim 2: Everyone can host content IPv6 reachable

If you are in the content or publishing business, you can easily have
your content reachable by IPv6. All bigger
[CDNs](https://en.wikipedia.org/wiki/Content_delivery_network) support
IPv6 and even if you happen to host on an IPv4 only web hoster,
there is
[via-ipv6.com](https://ungleich.ch/u/blog/enabling-ipv4-only-sites-for-ipv6-only-networks/),
a proxy service enabling all your IPv4 content by IPv6.

And we don't
say you should be using that service, you can also easily build it
yourself: you can use any IPv6 only VM and you can setup a proxy for
yourself.

## Claim 3: The world is now really moving towards IPv6

We know, there was this very, very unfortunate miscommunication many
years ago that we already ran out of IPv4 addresses. That was
only IANA running out of blocks to assign to the RIRs, however the
RIRs
([RIPE](https://www.ripe.net/),
[APNIC](https://www.apnic.net/),
[AFRINIC](https://www.afrinic.net/),
[lacnic](https://www.lacnic.net/) and
[ARIN](https://www.arin.net/)) did have plenty of IPv4 addresses
left. This situation changed since 2011 and now
ARIN is really out of IPv4, RIPE
is likely to run out of IPv4 in 2019. LACNIC and
AFRINIC are soon (probably 2020) to follow. APNIC on the other hand is already having a **per resource
fee**, which let it run out of IPv4 slower.

But, and there is the big but: APNIC slowing down the IPv4 run out has
a cost. And the cost is for companies who are relying on IPv4
addresses. So if you are in the APNIC region, you already pay around
1800 AUD for a /22 IPv4 network yearly.

The situation is somewhat similar in the regions that are running out
of IPv4, only that you need to buy or lease your IPv4 space there from
some market. The price for an IPv4 address is around $25 at the
moment, so if you were to buy a /22 IPv4 network, you would have to
spend more than $25'000. And this is not feasible for most SMB.

Even if you don't acquire IP addresses directly from a RIR and
run your service on a
[cloud like GCP, you begin to pay more for IPv4
addresses now](https://news.ycombinator.com/item?id=20742965).

So what is the alternative? It clearly is IPv6. Not because
there are many IP addresses in IPv6, but because
**IPv6 is affordable**.

So in short, why the world now really moves to IPv6:

* IPv4 now becomes a real cost factor
* It is not easy to acquire additional IPv4 space anymore
* IPv6 is economically more feasible
* We take the way of the least resistance, which is now IPv6

## Claim 4: IPv6 will re-enable end users

Due to the long ongoing IPv4 shortage, we are very much used to
[NAT](https://en.wikipedia.org/wiki/Network_address_translation). Some
people even believe that private IPv4 addresses are more secure,
which, generally speaking, is a bogus claim. You still need a
firewall, as you do with IPv6.

The bigger problem with private IPv4 addresses is that users have been
taught that they cannot reach each other directly. And this eventually
led to the rise of cloud services, because people were unable to reach
each other or to exchange data directly.

The Internet was built with the idea that everyone can reach everyone
else directly. NAT was only introduced due to the shortage of IPv4
addresses.

With the advent of IPv6, there are many "new old" ways of how we can
work together.

## The changes of IPv6 to the world

In the next articles we will describe some real, practical changes of
what we use and how we can work differently with IPv6. If you already
have suggestions, we are happy to read them on **ipv6 at ungleich.ch**
or on the [IPv6 Chat](https://IPv6.chat).
