I'm confused: dnsmasq won't cache a negative answer if it has no 
upstream servers. To cache a negative answer it has to _receive_ a 
negative answer (and the negative answer has to have certain 
information, notably an SOA record to determine the TTL for the negative 
answer.

Whatever is going on, it's more complex. Maybe the problem is that 
dnsmasq gets a negative answer from some upstream server, and then gets 
a new upstream server which has the correct information? The solution 
then is --clear-on-reload but I think NM sets that?


Cheers,

Simon.
