I have been assigned the couple name servers (NS) brynne.ns.cloudflare.com and chase.ns.cloudflare.com with my account. I used them to validate the configuration of a domain on Cloudflare. Let’s call it xxx.com.
I have a free plan. Everything is working fine. I can access xxx.com and the DNS checker tools provide me with the right info (NS are brynne and chase, DNS zone is the one I expected).
But I would like to use different Cloudflare NS for each domain name on this account. I would not like to use vanity NS (ex: ns1.xxx.com and ns2.xxx.com). I would like to be able to use any of the NS of Cloudflare.
So I changed randomly the NS on my registrar (namebright) to deborah.ns.cloudflare.com and katelyn.ns.cloudflare.com.
The domain xxx.com is accessible… But I still see brynne and chase as NS on tools!
But in my case the NS still point to Cloudflare, just a different NS than the ones associated to my account. And yes, the 2 NS are the same accros all domains, so I believe the NS are assigned on an account level (at least in free plan). But I would be very happy to find an option to force new NS for my domains on a same account.
