Now explain how you find a recursive nameserver that isn't listed in an NS
entry and *hasn't* been publicized someplace that Google can find it.

The same way you find open mail relays, SSH hosts with weak
user/password combos, bad WordPress installs, etc. - scan for them.  If
it is open to the Internet, it will be found (or probably already has
been).


Let me rephrase the question… How do you find an open IPv6 recursive name server
that isn't listed in an NS entry and hasn't been publicized someplace that Google can
find it?
