hi,
I think this dnsmasq lightweight version is always doing negative-caching for an indefinite time of period, and it should have a flag to disable it.
This is the formal dnsmasq flag for it:
-N, --no-negcache
Disable negative caching. Negative caching allows dnsmasq to remember "no such domain" answers from upstream nameservers and answer identical queries without forwarding them again.
