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.
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).
