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 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.

Request

curl --location --request PUT 'https://dns.de-fra.ionos.com/secondaryzones/a1bc82de-4cc5-40ca-bfb3-4e93bd9a367c/axfr' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJraWQiO'

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

curl --location 'https://dns.de-fra.ionos.com/secondaryzones/a1bc82de-4cc5-40ca-bfb3-4e93bd9a367c/axfr' \
--header 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJraWQiO'

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

curl --location --request DELETE 'https://dns.de-fra.ionos.com/secondaryzones/d8ff66f6-6777-42a8-b363-7f80b9105db4' \

Quota

To retrieve the quota of secondary DNS zones, perform a GET request to the /quota endpoint.

Result: On a successful GET request, you receive a response containing the quota limits and quota usage for your contract.
