+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).
+
+Meanwhile, if you are
+interested in giving IPv6 only VPS a try, there is a 50% discount only
+until [Black IPv6
+Friday](https://swiss-crowdfunder.com/campaigns/black-ipv6-friday?locale=en).

-## Summary and Outlook
-
-Centralisation is a danger to everyone. It concentrates decision power
-and effectively can censor opinions and in the worst case even ruin
-businesses. With IPv6 you can back in control. Even better, you can
-be part of driving decentralisation.
-
-Soon upcoming is the [Black IPv6
-Friday](https://swiss-crowdfunder.com/campaigns/black-ipv6-friday?locale=en),
-where you can get direct IPv6 experience. Or you can exchange your
-ideas for decentralisation on the [IPv6.Chat](https://IPv6.chat).
