I thinked previously this is an excellent site. So, I tried to register for their services. The registration form had not accepted my email address. I tried to use few others; always the same result. Finally, I typed the address I have from my ISP; not accepted too. So, I think now that they just ask humans to provide many e-mail addresses to collect these e-mail addresses.

Great site perfect for getting an IPV6 connection when your ISP doesnt currently support IPV6 its completely free but will cost you virtual credits to request a tunnel but you also gain credits by keeping the tunnel in good condition and reachable. you also cant Buy credits as the credits have no monetary value. you start out with enough virtual credits to request a tunnel once you make a FREE account. its complicated to set up and you have to refer to thirdparty sites like wikipedia to understand how to get it set up properly. but once its set up you will be able to have access to ipv6 sites. Overall i give this site a good rating it has tools to help you with ipv6 tunnel diagnostics. though this site IS NOT FOR THE COMPUTER NEWBIES. that being said you do need a fair amount of networking knowledge to let this site be of any benefit to you.
