One of the questions is, why do we depend on centralised +services at all? The reason for this is that there are not enough IPv4 +addresses and for that reason we use NAT to hide multiple devices +behind one IPv4 address. Wait what? Let's take it a bit slower. + +## How NAT works + +In the old times of the Internet, every device in the Internet used to +have a public IPv4 address. However when the number of devices began +to exceed amount of officially available IPv4 addresses, NAT was +introduced and it works as follows: + +![IPv4 NAT](/u/ipv4nat.png) + +Many devices are hidden behind one Public IP address. So for a phone +to communicate with another phone, it needs to connect via a +central, publicly available IPv4 server. + +## How IPv6 solves the problem + +In the IPv6 world, there are enough IP addresses available. +So every device, every smart phone, every alarm clock, every computer +can have a public IP address. Because every device can have a public +IPv6 address, they can communicate directly with each other: + +![IPv6 direct connections](/u/ipv6direct.png) + +## How to communicate with IPv6? + +So how does it look like with IPv6? Instead of relying on a central +entity (Apple in this case), you can directly connect to the phone of +your friends. This way, you could even use your standard browser like +Firefox, Chrome or Safari to write a message to your friend's phone. + +## So, what to do now? + +At the moment IPv6 is picking up pace in deployment and ISPs +everywhere in the world are moving forward with it. However, if you do +not have IPv6 connectivity, we [provide IPv6 +VPNs](https://ungleich.ch/ipv6/vpn/) that enable you world wide to +have IPv6. + +## More IPv6 + +If you are interested in IPv6, we invite you to join the [IPv6 +chat](https://IPv6.chat) or [follow us on +Twitter](https://twitter.com/ungleich). diff --git a/content/u/blog/how-to-enable-ipv6-in-applications/contents.lr b/content/u/blog/how-to-enable-ipv6-in-applications/contents.lr index 55804b2..17240c4 100644 --- a/content/u/blog/how-to-enable-ipv6-in-applications/contents.lr +++ b/content/u/blog/how-to-enable-ipv6-in-applications/contents.lr @@ -2,7 +2,7 @@ title: How to enable IPv6 in applications --- pub_date: 2019-09-26 --- -author: Team ungleich +author: ungleich --- twitter_handle: ungleich --- diff --git a/content/u/blog/how-to-support-open-source/contents.lr b/content/u/blog/how-to-support-open-source/contents.lr new file mode 100644 index 0000000..8a859bf --- /dev/null +++ b/content/u/blog/how-to-support-open-source/contents.lr @@ -0,0 +1,30 @@ +title: How to support Open Source +--- +pub_date: 2019-10-08 +--- +author: Nico Schottelius +--- +twitter_handle: NicoSchottelius +--- +_hidden: yes +--- +_discoverable: no +--- +abstract: +How to support Open Source as a hosting company +--- +body: + +## TL;DR + +Anyone who is working on a serious open source project can apply +for a free IPv6-VM and free IPv6-VPN. + + + +## More information + +You can get in touch with us via + +* email: info at ungleich.ch +* chat: [chat.ungleich.ch](https://chat.ungleich.ch) diff --git a/content/u/ipv4nat.png b/content/u/ipv4nat.png new file mode 100644 index 0000000..f29619b Binary files /dev/null and b/content/u/ipv4nat.png differ diff --git a/content/u/ipv6direct.png b/content/u/ipv6direct.png new file mode 100644 index 0000000..02c5e6e Binary files /dev/null and b/content/u/ipv6direct.png differ
