Hi Hanru,

Thanks!

Yes, since when you are performing the first type of query, you are 
simply asking whether an IP address is an active Tor server or not, 
of any kind. Now, if anyone wanted to see if your Tor server would 
exit to their location or not, they could perform the second type 
of query (See my original post for details on the two query types, 
if necessary), which, in your case, would always return NXDOMAIN 
since you don't allow any exiting.

Hope that helps!


Best regards,
