The DNS feature included in Danube Cloud enables a simple management of DNS domains and records.
|DnsAdmin||read-write on DNS records (DC-bound domains only)|
In the upper right corner is a button labeled Show All, which can be used to display all domains, including domains that are not associated with the current working virtual data center.
DNS service has recursion enabled for all network subnets that are defined within networks list in Danube Cloud installation. All other (=external) IP addresses will receive only authoritative responses (domain must be present locally in the domain list).
