I have a domain with multiple subdomains that I’d like to add to Cloudflare. The subdomains are configured using A records.
When I added the primary domain to Cloudflare, I did not see the A records when Cloudflare queried the DNS records for the primary domain.
The question is, how can I make sure that the sudomains’ A records will be carried over to Cloudflare once I change the Nameservers for the primary domain?
You can import a zone file. If you can’t export it from your current control panel ask your hoster/provider if they can provide you with an export. It needs to be BIND compatible.
