Example configuration for DDNS on root level domain and not dedicated subdomain.

[tylerdmace]

Hello!

The only configurations I've been able to get working with this software is using a dedicated subdomain for serving dynamic records (eg, host.d.example.com as detailed in documentation) but what I'd really like to do is allow subdomains to be created right off the root domain (eg, host.example.com) without the need to subdomain off of d.example.com. Is this possible and if so, can anyone share with me exactly what this configuration would look like?

Possibly not, and most likely you wouldn't want that anyway.

If you don't use a subdomain, it means you would be setting the NS records of your root domain to point to this host, effectively making the built-in PowerDNS container your domain DNS! You would have to setup up all your DNS records there, including MX, CNAMES, A/AAA, TXT, etc. Your current DNS (most likely from your Registar) would stop working.

I'm not sure how functional the built-in PowerDNS is as a fully-fledged general DNS server. It wasn't designed for that, so most likely was not configured for that use-case. It possibly has no Web UI and no API, at least none that is exposed to the built-in Caddy HTTP server.

And even if you manage to make it work, there's the issue of availability and security: are you willing to self-host your domain's entire DNS?

That said, this is the workaround I use:

• Let DDNS do its job and create the entries on hostname.d.yourdomain.com
• Manually create a hostname CNAME record in your DNS pointing to hostname.d.yourdomain.com
  This is a one-time setup, for long-living hostnames you manually pick to expose to your root domain.
