Prerequisite: Before creating a secondary DNS zone with IONOS Cloud DNS, ensure that the primary zone is capable of establishing a zone transfer with the secondary DNS server; this means port 53 is open for TCP and UDP connections.
To create a secondary zone on the IONOS Cloud DNS, follow this step:
Perform a POST request to the /secondaryzones endpoint by providing the zoneName, description, and primaryIps for the IP address of the primary nameserver.
Note: For sending DNS notify messages, Cloud DNS uses following Anycast addresses: IPv4 212.227.123.25 or IPv6 2001:8d8:fe:53::5cd:25.
Result: On a successful POST request, you receive a response containing the secondary DNS zone UUID, Name Servers, primaryIps, and the request status.

Initiate zone transfer to a secondary zone
Note: The creation of a secondary zone initiates zone transfer. In case of disrupted network connectivity at this time, you can initiate the zone transfer manually between the primary and secondary (i.e. secondary name server could not access primary nameserver on port 53) zones.
To initiate zone transfer from the primary zone to the secondary zone, follow this step:
Send a PUT request to the /secondaryzones/{secondaryzoneId}/axfr endpoint.
Note: For sending DNS notify messages, Cloud DNS uses following Anycast addresses: IPv4 212.227.123.25 or IPv6 2001:8d8:fe:53::5cd:25.
Result: On a successful PUT request, you receive an HTTP response 200 OK.
