Question Reverse DNS Lockup shows all (main) domains on server

[Azurel]

With Tools like this Reverse IP Lookup you can list all subscription main domains on a server with plesk.
Example with Plesk.com IP: Reverse IP Lookup
Is this really neccessary? Can this be deactivated without side effects?

Hey Azurel

This cannot be deactivated, since all your domains resolve to the same IP address. What a Reverse Lookup does is just the opposite. It checks which other domains are resolving to this IP address.
When you want to hide this, you can proxy your traffic through a network like Cloudflare.

Hope this helps.
