This website allows to increase security and ensures real ip of your server is hidden from the eyes of malicious users. But you should not use direct ip of your server to connect with your domain, if you use so some other tools like dns history logger will catch your real ip.
See the following website, may be you are now behind cloudflare, but your past will track you down.
Get past dns records of domain.

I think the best way of hiding an IP is not to hide it. Like by hiding it you're first in line for bots that are created by your more sophisticated Website hosts to catch those who are hiding their IPs. Like malicious users are the first guys who are trying to hide their IP when they are doing their bad deeds. The same technology that is developed in bots and filters to catch the malicious users, will also catch those honest users who are trying to hide their IP - with the difference they won't be seen as "honest users". They'll be seen as users who are hiding their IPs - so have something bad to hide.

The same with the security measures of Google that have been going into overdrive. I've been having issues with my e-mail account - it got blocked once for no reason. And yesterday someone said their e-mail to me got returned. Collateral damage for Google's many new security processes, bots, and filters?
