[Dnsmasq-discuss] Using a variable in the address option in dnsmasq.conf

[Petr Menšík]

You can use any script to generate those addresses into separate file.
Dnsmasq is very low overhead server without real built-in scripting for
these things. It already contains lua interpreter, but I think such
features should be left to external scripts instead.

You can already use:
conf-dir=/etc/dnsmasq.d

and then generate your file any way you need. For example in bash

echo "# Autogenerated file, do not edit by hand" >
/etc/dnsmasq.d/blocked.conf
for DOMAIN in 2o7.net 2mdm.net
  do echo "address=/$DOMAIN/$MYIP" >> /etc/dnsmasq.d/blocked.conf
done

I think this is simple enough for any reasonable use. Why should dnsmasq
have it built-in?
