Hello there, New to this platform, but already love it. I have setup my own Debian 10 master-slave forward/reverse DNS setup with nginx and apache, respectively, setup a domain and several vhosts, all of them using free, valid certs. Everything seems to be working beautifully. Now I'd need to do something maybe rather uncommon. I need to properly resolve domain names to their real IP addresses only for the DNS records already configured on the administration panel; for the rest of the DNS queries my two servers receive, i.e. for domains that are not configured on these machines, I would like to reply always with the same IP address, that points to another machine I already run elsewhere. I understand I can configure wildcard DNS for subdomains, but what can I do for root domains?
