DNS Services that Allow Subzones/Subdomains? (lemmy.world)

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.

DNS points to the domain. Then you configure the subdomain on the same IP. Maybe I'm missing something, but this is how I understand subdomains.

Decent DNS providers allow you to create NS records for subdomains.
This delegates the subdomain and all of its subdomains to another DNS.

Useful for companies that want to control their own records, but might want to allow a group of developers control over app.example.com and all subdomains, without the developers having to pester the company for record updates.

Also used for acme-dns, which is a self hosted DNS designed to only deal with txt records for acme DNS challenges (ie lets encrypt).
Means you can limit the possible disaster of the DN API keys being leaked (an attacker can only generate TXT records, instead of rewriting all your DNS records)
