Cloud Flare connection and configuration, how to hide the real IP of the site?

Question

Domain Name System

Hello, tell me how to properly connect and configure Cloud Flare (hereinafter referred to as CF) to hide the real ip address of the site? Maybe you need to use a paid package that CF offers? the fact is that when you enter an A-record, you need to specify the IP address of the site (server), then change the NS, there are no questions, after that, through any check (for example, who.is) shows that the site works through CF. But after all, any user (registered on CF) can enter the domain on CF and see the specified A-record, where the IP of the site (server) will appear. Apparently I don’t understand something, since I had a similar question, but I checked some sites that work through CF, and so they have the minimum number of entries displayed there, they mainly relate to mail and there is no useful information for attackers. There are specialists in setting up CF? Thanks for the answer
