http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/effective_tld_names.dat?raw=1 http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/ef... .cz.cc is not on that list, nor should it be. This is a free "domain" generator using subdomains of cz.cc. Hence, all of the subdomains are grouped together. I don't see anything wrong here.
