Thread:Project:Support desk/change domain/reply (4)

Just FYI, dot.tk is not a domain, just a web redirect. You can't assign dot.tk an IP address, publish another service (mail, ftp), etc.

If you ever attempt to put a dot.tk domain in $wgServer, no edit will be saved, since all requests will go to dot.tk, not your IP address, and the POST data will be lost on the redirect.

That doesn't happen with a dyndns service.
