As my new provider uses a special kind of dual stack system I was finally confronted with _IPv6_ and want to summarize my experiences in this article. Besides the promise of a better bandwidth and despite my good experiences with their connection over many years the main reason for considering alternatives to _Telekom_ was that they don't offer the kind of Internet-only package I wanted. At first I also considered a _O2_ _DSL_ connection because I already use their mobile offerings but as I recently suffered problems with their contract management when they mixed up my contract with the contracts of my family members I opted to disregard them in favor of _Unitymedia_[^0]. @@ -8,7 +8,7 @@ After some initial confusion when I received the router days before my connectio ## Remaining problems with _Unitymedia_ -As I still work as a part time software developer at my former training company but live in Karlsruhe I do most of my work remotely. While the bandwidth requirements for this task are neglible some of our customers require _IPSec_ based VPNs in order to access their _SAP_ systems. Sadly the special IP-packets required for this kind of VPN seem to be dropped by _Unitymedia_ which means that I require an additional _Level-2_ VPN to a non-dropping connection in order to use these VPNs.

But all things considered this is still an acceptable tradeoff. If one reads forum and blog posts concerning _Unitymedia_'s service one will find lots of whining about their _DSlite_ technology for providing a dual stack _IPv4_ and _IPv6_ connection. This is mostly because they don't seem to have enough _IPv4_ addresses to offer each customer their own address. This means that _IPv4_ addresses of _DSlite_ connections are shared between multiple customers[^2]. The only globally accessible address each customer gets is a _IPv6_ address - for each device connected to the router. -- cgit v1.2.3
