Ok, i fixed it (wrt my particular request) and i'll post what i've got here in case it helps someone else. For extra clarity I am a bit confused about the different between 'tag' and 'set' and in googling have found references to both, a short and clean definition of these would be great.Can i specify different DNS servers, for different tagged networks?.Can i make everything default to 'green', unless explicitly set to 'red' by MAC (at the moment I am having to explicitly put the mac of everything into the conf file)?.I believe the dns server is not being handed out because a 'cat /etc/nf' on one of the hosts shows 127.0.0.1. This does not seem to work however, I have different hosts being assigned different ip addresses based on whether i have matched their MAC, and then it seems as if the dns server is not correctly being handed out. I would then like to say 'for all green tags, give them dns server A as their resolver', 'for all red tags, give them dns server B as their resolver'. I have this part working successfully (I believe), where i explicitly set it by MAC - but what i would like is for everything -unless specified otherwise- to default to green. I would like dhcp leases to be handed by, by -default- tagged green, except for a few specific MACs where I would like to hand out the red tag.

I'd like to split my network into dnsmasq tagged subnets, for this example say: Default to dns server A, unless explicitly set to dns server B per host (mac). As an overall solution i'd like to split dns resolving between different servers, using dnsmasq.
