This is a quite simple utility for managing NXDOMAIN static DNS records driven by RouterOS. You will be able to specify as many hosts files you have and get a sorted and uniq bundle as a .auto.rsc script.

The resulted bundle has a form:

:do {
    :local hosts {"example.com";"sub.+\\.example\\.com";};
    :foreach host in=$hosts do={
        :do {
            :if ($host ~ "\\.\\+") do={
                /ip/dns/static/add regexp=$host type=NXDOMAIN comment=example;
            } else={
                /ip/dns/static/add name=$host type=NXDOMAIN comment=example;
            };
        } on-error={ :nothing };
    };
};

I've added a submodule which contains a curated list of hosts, in case if you don't have any.

See mkadlist.sh before you hit it and change it for your needs.
