Create a Secondary DNS Zone
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 thezoneName
,description
, andprimaryIps
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.
Request
Response
200 OK
Check zone transfer status
To check zone transfer status, follow this step:
Perform a GET request to
/secondaryzones/{secondaryzoneId}/axfr
endpoint.
Result: On a successful GET request, you receive a response for AXFR communication status for each of primaryIps.
Request
Response
200 OK
Response Fields
Field | Type | Description | Example |
---|---|---|---|
errorMessage | string | Error message if any | |
primaryIp | string | Primary IP address | 192.0.2.2 |
status | string | AXFR communication status | OK |
Delete a secondary zone
To delete a secondary zone from the IONOS Cloud DNS, follow this step:
Send a DELETE request to the
/secondaryzones/{zoneId}
endpoint.
Result: On a successful DELETE request, you receive an HTTP status 200 Accepted.
Request
Response
200 Accepted
