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.
I’ve hosted subdomains on namecheap for 10+ years. It’s point and click if you use cpanel or just edit DNS records if you selfhost.
Maybe I’m not reading your question right?
Yeah, I use subdomains on namecheap just fine. The support wildcards too; I have an A record for *.sub, so a.sub.domain.com and b.sub.domain.com, etc. all get resolved to the same host.
You can probably create an NS record for sub.domain and have it work. I haven’t tried it, but I can type it in namecheap’s site and it looks like it’ll accept it if I hit submit (i.e. none of the fields have red validation errors).
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.
