I understand how Cloudflare assigns a unique pair of nameservers to each account; however, for the past few months, new domains I add to my account will either have my original Cloudflare nameservers, or a pair of new ones. This is breaking our automation setup. I’d like to know if this is a bug, or intended behaviour?
Normally you get the same nameservers, but it’s not guaranteed. They may change if the domain has been on Cloudflare before, or other reasons.
If you want fixed nameservers, you can use account vanity nameservers (requires a business or enterprise domain in the account) or tenant custom nameservers…
