Why am I being charged for Cloud DNS even though I have no DNS zones in my cloud?

Public DNS requests from VMs to Delphi Cloud DNS servers are also charged.

Thus, Cloud DNS may still be used even if your cloud does not contain any DNS zones other than service ones.

We recommend using caching resolvers, such as systemd-resolved, dnsmasq, or unbound. These reduce the number of public DNS requests, and thereby, your costs.

Can I get logs of my operations in Delphi Cloud?

Yes, you can request information about operations with your resources from Delphi Cloud logs. To submit a request, contact support.

How do I register a domain name using non-Latin characters?

Cloud DNS supports any domain names, including those with local characters. To create a domain name with non-Latin characters, use Punycode.

How do I delegate reverse zone management to Cloud DNS?

To delegate reverse zone management to Cloud DNS:

  1. Confirm that you own the domain zone (dedicated IP). To do this, just provide a copy of the document confirming ownership right transfer and registration information from the RIPE database that identifies IP ownership.
  2. The Delphi Cloud information security team will verify the data you provide and notify you of the results.
  3. After your data has been successfully verified, contact support.
