tunnelbroker.net, operated by Hurricane Eletric (he.net) ^Register, setup IPv6 over IPv4 tunneling. They can give you a whole /48 if you want to play with your network. Now considering you want to test other sites, all you need is IPv6 connectivity, so the default settings they provide are enough. I recall they had decent docs on how to set things up for all major OSes. There were a few gotchas : * you need to make sure "ip proto 41" is not filtered by your firewall, or you won't be able to setup the tunnel * in the web interface, make sure you provide your public IPv4, and not your NATed address.
