I need to add a wildcard address record to dnsmasq running on OpenWRT.

If I were to call dnsmasq from the command line, it would look like this:

dnsmasq --address=/#/123.123.123.123 ...

I would like to use UCI to configure dnsmasq, but I am having trouble figuring out how to add this option.

One complication is that I have two instances of dnsmasq configured for my different interfaces. So, I have two config dnsmasq <some name> sections in /etc/config/dhcp. Unfortunately, I need to add this wildcard to only one of the sections, so I don't think I can use /etc/dnsmasq.conf to specify this option as it would then apply to both instances (if I understand correctly). And, unfortunately, there doesn't seem to be an option that allows me to specify an additional dnsmasq.conf for just one of the interfaces.

My first thought was to add an option addnhosts ... to specify another hosts file just for one of the instances, but it seems like hosts files don't support wildcards.

Is this possible somehow? If so, how?

Turns out there is actually an undocumented list-option called address that does the trick...

list address '/#/123.123.123.123'

I guess that makes sense... :)
