One of my client has two domains names linking to a website :
Domain A
Domain B
The problem is that the client doesn't want to let us manage the DNS of the domain A and they don't want to link it to Cloudflare (we don't really know what they want to do with the DNS of this domain). They only allow us to manage the Domain B.
Is there a way, somehow, to have the Domain B linked to Cloudflare and their Domain A linked to the Domain B which is linked to Cloudflare ? Like this, if they try to access the website from Domain A or Domain B, they both benefit of Cloudflare.
(I hope I didn't say something really stupid, DNS management and CDN are still a new concept to me - if I did, please excuse me)

Probably would need more details in a support ticket. Based on what I'm reading, however, you can't point a domain not on CloudFlare to one on CloudFlare (can cause DNS resolution errors).
If the client doesn't want to switch the domain to us entirely, then they could look at doing a CNAME setup.
