You might want to look at the 'localise-queries' option.

Thanks for the hint, that's more or less what I was looking for (I saw
it comes with no IPv6 support but I'll try to implement that myself and
send the patch if I have time).

Such a patch would be very welcome.


I still think it could be cleaner if you could tell dnsmasq to use
different hosts files depending on the subnet (with a default one) as
that'd prevent queries from non configured subnets from getting all the
entries instead of the desired one. For example I may query the address
of a file server from the router, since the 127.0.0.1 network isn't in
the same subnetwork as the fileserver this would give me all possible
entries despite I may want only the one corresponding to the network
administration VLAN to be given.

I suppose addn-hosts could be expanded to do that, but I'm not sure if
dnsmasq now supports more than one entry of this kind.

You can certainly have more than one --addn-hosts file, but you can't associate them with particular interfaces.

The simplest way to do this is probably just to run multiple instances of dnsmasq, each bound to a particular interface.


Cheers,

Simon.

Anyways the improvement is deployed and working for now thanks to you :)

If you use 802.1q vlan and bring the these directly to the router
(running dnsmasq) and assign the two different networks to the
interfaces, dnsmasq will just do this correctly.


dhcp-range=10.10.0.1,10.10.255.254,4h
dhcp-range=10.60.0.1,10.60.255.254,4h

These lines will just find the correct interface and supply the correct
DHCP records.
Yes, yes I know, I added the tag:vlan.xx just as a safe measure but
thanks for the pointer.

Thanks again for the pointers, I suppose I'll use localize queries for now.
