I did a whole lot of checking. Tor (tor.eff.org) DOES resolve from within the
NGT network. Some DNS names resolve and other's don't when using their
nameservers from outside (which I did).
However, NGT and Telenor DOES give false DNS replies to many sites. I've put
all testing information regarding this here:
It seems that there is a shared list where NGT redirects to 220.127.116.11 and
Telenor to 18.104.22.168 on a given list of DNS requests. These both show
the same page which say you're a bad person.
