Cloudflare DNS: Create top-level subdomains without requiring the main domain

[iliajie]

Hello Jamie!

I know we’ve discussed this before, but I want to document it for others.

Consider an admin managing 10 virtual machines, each using Cloudflare DNS. The main DNS zone for a domain (e.g., virtualmin.dev) is controlled by the main virtual machine. The other virtual machines also need to use Cloudflare DNS for the same virtualmin.dev domain, using subdomains like test1.virtualmin.dev, test2.virtualmin.dev, etc.

Currently, to make this work, I have to create virtualmin.dev on each of the other 9 virtual machines. This creates overhead and risks messing up the main DNS records, as Virtualmin flags and complains about mismatched IP addresses and suggests fixing them on each machine. This limitation is also frustrating.

Is there a way to allow the other virtual machines to use top-level subdomains without having to recreate the main virtualmin.dev DNS zone on each machine? Perhaps as an optional setting?

I'll put this on my TODO list to look into .... maybe it will be possible to support, since I can see it being useful for customers with many boxes.

I’ll look forward to testing it once it’s ready. Thank you again!

Jamie, any update on this?

I haven't forgotten about this, but still haven't had time to implement it..
