This is a short paper I wrote in the context of a course at my university.

You might wonder why I chose this topic, and there is a pretty simple explanation:
When I moved to Stuttgart and got a new Internet Service Provider, I only got a Dual-Stack Lite connection to the Internet, meaning that I got a public IPv6 address, but no "real" IPv4 address. This normally doesn't matter, except when you try to reach a device that is in your home network from outside this network. This, in my case, was necessary in order to be able to reach my smart home control unit (raspberry pi xP), e.g. to automatically turn off the lights when I leave the house. So with the new ISP this couldn't be done any more using IPv4, hence I thought: "no problem, lets just do everything with IPv6". Well, theoretically this would have worked, only problem is, that my Mobile Network Operator (Simyo/E-plus) neither is supporting, nor plans to support IPv6 in the near future.

That is why, when we had to choose a topic for a paper in our Mobile communication systems - class, I decided to look into the matter of IPv6 in mobile networks.

 

P.s. For reaching the raspberry over IPv6 from an IPv4 only network I eventually used the tunnel broker feste-ip.net
