Some FREE DOMAIN websites[LEGAL]

[Zach]

They all have their downsides.
With co.cc, if you forget to renew your domain, getting it back is a pain in the a**.
Cz.cc has ridiculous amounts of downtime that can be devastating to a popular site.
Dot.tk requires that you get a certain amount of visitors, and they seem very trigger-happy when it comes to cancelling domains and holding them for ransom.
FreeDNS is a ghost town, and the domains under it (us.to, vr.lt, etc.) have no guarantee that they will be renewed to prevent the loss of thousands of domains. Also, you can properly register only two and a half domains per free account.
