I have a domain,
example.com which is managed on Cloudflare, and I would like to manage multiple sub-sub-domains, that end with
.internal.example.com, such as
two.internal.example.com on route53, while still managing
example.com and the rest on Cloudflare.
According to this answer, I understand it's possible to manage one sub-domain on different nameservers, but how do I manage multiple sub-sub-domains?
Am I forced to create a nameserver entry on the TLD (Top Level Domain) for every sub-sub-domain or can I use a wildcard or some other method to only add one nameserver entry on the TLD?
