I own the domain htmljatekok.xyz which is linked through cloudflare to an active IF hosting account. I would like to link a subdomain of the main domain to a different IF account, is this allowed by TOS and possible in any way? I have tried adding the subdomain but I get the “already added to an account” error message.
And I want to avoid having to change nameservers again, as that would cause my main site temporarily to bypass CF protection.
If you have htmljatekok.xyz hosted on one Hosting account, then that domain and any of its subdomains will also be created on that hosting account. It isn’t possible to host the top-level domain on one Hosting Account and a subdomain on a different one.
All limitations are technical. In order to have a domain on its own account, you must be able set nameservers for that domain. Since it is impossible to set nameservers on a subdomains, you cannot do what you want to do.
You can however, add the subdomain to the IF account that has the main domain, and add it to Cloudflare using the guide I linked above. It will have its own filemanager section, so the two sites will not share the same files.
Is there a specific reason that you want to do this for?
Those are different. It’s confusing, but there are two different types of records. there is the DNS NS record (They one you show), and the domain nameservers (What you need to set).
