CNAME from outside Cloudflare to CNAME in Cloudflare

[user5255]

(All domains are examples)

I have the following domain setup with cloudflares Name servers.

shop.com

with the following DNS setup in Cloudflare.

CNAME JasonsStore1.shop.com >> JasonsStore1.azurewebsites.net

CNAME JasonsStore2.shop.com >> JasonsStore2.azurewebsites.net

CNAME JasonsStore3.shop.com >> JasonsStore3.azurewebsites.net

Can I CNAME from another name servers outside of Cloudflare e.g.

CNAME JasonsTShirts.com >> JasonsStore1.shop.com

CNAME JasonsJumpers.com >> JasonsStore2.shop.com

CNAME JasonsShorts.com >> JasonsStore3.shop.com

So the path to get to the final website would be:

Name server not Cloudflare > Cloudflare Name server > end website

JasonsTShirts.com > JasonsStore1.shop.com > JasonsStore1.azurewebsites.net

I note there is a support page on CNAME setup which requires a business account - is this a requirement to achieve the above?

If this is so then:
-Is the cname request in the instructions for the domain shop.com (e.g. one request)
OR
-for each domain external to Cloudflare e.g. JasonsTShirts.com, JasonsJumpers.com, JasonsShorts.com.

Thanks

Bad idea

Can I CNAME from another from name servers external to cloudflare e.g.

You generally can’t point CNAME records to Cloudflare as the proxies will need to recognise the domain and won’t if the domain itself is not on Cloudflare. That is regardless of your plan level and that domain will always need to be “registered” in some way with Cloudflare.

This is, of course, under the assumption you are talking about proxied records. If they aren’t Cloudflare is not involved in the first place.
