Feature request: Block scanning of domains and IP address/ranges

[Geekujin]

I've got this deployed on an LXC container via the Proxmox Helper Script and so far I'm olving it, great job! I'm using it behind a reverse proxy and noticed that if any of my LAN IPs are scanned or the domains served by my proxy, there's some info exposed such as open ports and local DNS server amongst others.

I'd love the ability to list 'blocked' domain names in a file, along with local IP ranges, and serve an error message when attempting to check them. Even something simple such as "operation not permitted" or similar.
