You have one external part, and one local part of the address. If you have an external tunnel broken, or isp, you get an adress which is put in front of your local adressspace. The local adresses is generated at your local machine (often based on mac address), and broadcasted to the ipv6 advertisement daemon.
Example; You set up a gateway to an external tunnel broken, put up radvd or similar as router advertisement daemon. Then you get a prefix from the tunnel broker which will be the first part of the address. Then all external calls to that prefix first hit your router daemon, which then sends the data to the correct 'internal' adress.
