Any suggestions for a DNS service that specifically allows subzones, also called subdomains and delegation of those subzones.
I’m currently using CloudFlare and NameCheap. It doesn’t look like NameCheap doesn’t support subzones at all, and CloudFlare only supports them at the enterprise level.
Cloudflare supports NS records, which is what you’re looking for. Except it probably only lets you create a zone for the top level domain, so you can only delegate to other providers. AWS Route53 will let you create subdomain zones, and will let you create NS records to set up delegation.
