We have a main domain managed on external DNS server. We want manage just a subdmain in Cloudflare.
Then, we have created a NS regsiter for the subdomain pointing tu primary cloudfalre dns of our account, and in the Cloudfalre panel control we have add a new site, import all DNS records, we have removed all this records just keep NS records pointing to our Cloudflare prumary DNS nameserver.
Its ok? or there are any setting we are missing?
