If you have been wanting to play with IPv6 but your upstream provider does not support it, an easy way to get yourself an IPv6 address is thru SixXS. They provide an easy way to get your very own IPv6 address with their AICCU client software. The software is available for many platforms including both Windows and Linux. All you need to get started is to create an account, install the software and run it; then magically your computer will have a new interface with an IPv6 address. The tunnel this software creates runs over UDP therefore you are doing IPv6 over a UDP tunnel. The software is NAT friendly so it should work fine thru most home routers. One thing to really consider is that once you are running the software your computer is now exposed directly to the internet with no network based firewalls, ids, etc to protect it. Make sure to configure any listening programs to not listen on the IPv6 interface that you do not want exposed to the internet. You can easily determine what port your machine is listening on its IPv6 address by running a “nmap -6″ scan pointing to your new IPv6 address.
