Subject: [Dnsmasq-discuss] feature request: ipset options


     I'm running dnsmasq with ipset support in some VERY low memory machines (those all-in-one boards), and RAM is really my main concern here. I'm actually using some 'ipset' rules on dnsmasq.conf to have some domains IPs on an ipset list and, thus, being able to allow/deny them with iptables.

     Some of the sets are REALLY large (10k+ entries).

     I was thinking on having a dnsmasq option for, instead of adding the full IP to the set, adding its /24 network for example (simple stripping last digit and adding '.0/24'). In that case, the sets would be significantly smaller. I know with this i'll pottentially allowing traffic i'm not looking for, by assuming th domain holds the entire /24 network. But i'm really concerned with RAM usage, and i'm willing to have that risk.

     Would it be hard to implement something like that in dnsmasq ? 
Would this be useful for any one else ?
