This section provides access to connectivity resources, in case you don't have native IPv6 connectivity from your ISP, such as our own tunnel broker, but also others located in different part of the world, so you can choose the one that is closer to your location and consequently obtain a better performance.
You will find also two more sub-sections. One is a "looking glass", a set of tools in order to do several network test and measurements from our server to any point in the network, which is useful to debug, for example your connectivity.
The other one are instructions to test if your Operating System is already configured with IPv6, and if not, simple guidelines to enable it.
