Re: fast fail on specific entries not defined in /etc/hosts

This one sounds like the most viable option for me. I can run a DNS resolver on the same host as the application is running on, and configure it just for this application, and change the DNS search order to consult this local DNS service first (and then the ones it currently uses). I can use multiple domains if needed (not just company.com).

You could use the local DNS server and configure this to forward everything else (not needing "special treatment") to the "normal" DNS servers. /etc/resolv.conf would need 127.0.0.1 only. Regards Peter
