Is it possible to determine the hosting if the domain is behind Cloudflare? How?

Question

cloudflare

Is it possible to find out the IP of the site, its hoster, etc., if the site is behind Cloudflare? What are the ways?

Answer 1

1. Upon request, they give out this data perfectly. Of course, we are not talking about a request from Vasya Pupkin.
2. Leaks often occur due to illiterate server settings, ranging from outgoing mail to more exotic options.
3. Usually you can find the IP address by history, and often it is not changed after connecting the CF.

Answer 2

No way. That's the point of Cloudflare.
