[Dnsmasq-discuss] Make dnsmasq answer requests from certain hosts only

Hi,

Is there a way to configure dnsmasq such that DNS resolution requests 
are only answered if they come from (trusted) hosts? This is to avoid 
DoS attacks on remote DNS servers.

If this is not possible within dnsmasq, do I understand correctly that 
the only way to do this is using iptables or similar?

Thanks.

Best,
Peter
