Cloudflare is not your hosting provider but a reverse proxy that sits in between your hosting and the internet. If you were not aware of this, I advise reaching out to your system administrator or the person that set up your website.
Take a look at your DNS records here at dash.cloudflare.com. You should have an “A” record that points to your actual host. You can paste that IP address into the upper right corner of whois.com and it will most likely clearly show you who your host is.
