Manage private DNS settings in a network

Last update:

Add a network to a DNS zone

If you add a network to a DNS zone, A or AAAA records will be created automatically for the network ports. If new ports are added to the network or existing ones are changed, A or AAAA records for them will be added or updated automatically. You can change the port domain name manually, and the record in the zone will be updated automatically.

The full domain name of the port (FQDN) in the record is formed as <server_hostname>.<zone_domain_name>., where <server_hostname> is the server hostname, and <zone_domain_name> is the zone domain name.

  1. In the Control panel, from the top menu, click Products and select Cloud Servers.
  2. Go to the Private DNS section.
  3. Open the DNS Resolvers tab.
  4. In the network row, click .

  8. Click Save.
