+body:
+
+Today we focus on one of the very obvious effects of IPv6: saving
+resources and thus money. This post is part of the
+[how IPv6 changes the world](/u/blog/how-ipv6-changes-the-world/)
+series.
+
+
+## The general way of saving money with IPv6
+
+Economically, the less of something exists, the more expensive it
+is. There is only one Mona Lisa and that one is quite
+expensive. Similar if you move out of a city
+(like to
+[Digital
+Glarus](https://hack.digitalglarus.ch/hacking-and-living-in-hotel-diesbach.html)),
+rent become more affordable.
+
+As stated in the previous post, it has gotten quite expensive for companies
+to acquire IPv4 address space and
+[the prices are
+rising](https://www.retevia.net/address-pricing-2019-and-beyond/).
+Compared to what we paid 2 years ago, the
+**market price is now 600% as high**.
+
+So as a company like us, when the cost is rising, we transparently
+forward the price increase to the end users to stay profitable.
+
+So if you opt out of IPv4, we don't need to buy more space and neither
+of us needs to spend money on it.
+
+## Most services work without IPv4
+
+And this brings me to the question of what one can do without an
+explicit IPv4 address. And the answer is: almost everything you could
+do with an IPv4 address.
+
+Here at ungleich we spent quite some time to allow a seamless
+migration to an IPv4 free world:
+
+* If you want your server to be reachable from the IPv4 Internet,
+  you can use our [IPv4-to-IPv6
+  Proxy](https://redmine.ungleich.ch/projects/open-infrastructure/wiki/How_to_use_the_IPv4-to-IPv6-Proxy),
+  which even works with HTTPS.
+* If you want to access something via IPv6, but you don't have IPv6
+  connectivity, we can provide you with an [IPv6
+  VPN](https://ipv6vpn.ch), which works even through CGNAT. It is also
+  free, if you have any VPS running from [IPv6OnlyHosting](https://ipv6onlyhosting.com).!
+
+There are rare exceptions of things that do not yet fully work, but
+we even work on these cases.
+
+## Saving money #1: IPv6 only VPS
+
+One of the most obvious gains is, if you decide to go with
+[IPv6 only VPS](https://ipv6onlyhosting.com/), because there you are
+directly rewarded more affordable prices.
+
+Be it Google, ungleich or our friends at
+[mythic beasts](https://www.mythic-beasts.com/), we are all in the
+same situation that IPv4 addresses cost us money.
+
+As a user, you even have the ability influence this
+development: the more IPv6 only services you consume and the less you
+rely on IPv4, the more it becomes the standard and the less everyone
+is depending on IPv4. It's a positive feedback cycle.
+
+## Saving money #2: Going IPv6 only
+
+Another very simple case is the network management in SMB and even
+enterprises. The bigger you are, the more networks you have to manage
+and in our experience, dual stack networks (IPv6+IPv4) are no fun to
+maintain and have rather high complexity when it comes to security /
+ACLs/ firewalling.
+
+However you will need IPv6 in your network eventually anyway. So the
+strategy that we recommend is to switch directly to IPv6 only
+networks.
+
+This way your network planning becomes significantly easier, also in
+comparison to IPv4 networks. You don't have to spend a lot of time
+into network planning anymore, as you can use a /64 for every
+individual networks.
+
+This way you reduce complexity and are future proven at the same time.
+
+## Saving money #3: Not using the cloud
+
+Another interesting aspect with IPv6 is to avoid cloud services at
+all. Instead of uploading your data somewhere and having somebody else
+downloading it again, you can easily share data or communicate with
+other employees directly using IPv6.
+
+## Saving money #4: The IPv6 Black Friday
+
+At the moment we run a special IPv6 promotion campaign
+named [Black IPv6
+Friday](https://swiss-crowdfunder.com/campaigns/black-ipv6-friday?locale=en)
+at which you can even get up to 50% discount on the already more
+affordable IPv6 only products.
+
+## More money saving?

+know on the [IPv6 Chat](https://ipv6.chat) and we will add the hint
+for others.
