hi i met this problem,

here is my dnsmasq.conf

HA1#cat /etc/dnsmasq.conf
domain-needed
log-queries
bogus-nxdomain=1.2.3.4

and the hosts file
HA1#cat /etc/hosts
127.0.0.1 localhost localhost.singtec.com
192.168.255.1 test.com
1.1.1.1 localdns

then i nslookup test.com, it can get the 192.168.255.1, But when i
quering a non-existent domain, the result is "*** Unkown  can't  find
xxxx,  Query refused

I thought it should return a 1.2.3.4 for the nxdomain !!
