Export a DNS Zone

Similar to retrieving a primary zone, you need to provide the UUID of the primary zone that you want to export.

Prerequisite: You need an IONOS Cloud account with API credentials configured with the appropriate permissions.

To export an existing primary zone at IONOS Cloud DNS in a BIND format, follow this step:

• Perform a GET request providing the zoneId of your primary zone.

Result: On a successful GET request, you receive the BIND file with the primary zone having the UUID assigned.

Request

curl --location --request GET 'https://dns.de-fra.ionos.com/zones/d6ba6fc1-fc82-4f0c-b030-2638778e0bef/zonefile' \
--header 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJraWQiO' \

Response

200 Successful operation

Zone file

The exported zone file is in BIND format, a widely used format supported by most DNS software, including the BIND DNS server.

The file includes all record types associated with the selected primary zone, including SOA record, NS record, Service (SRV) record, and configuration information such as TTL values.

An example of a file in BIND format with an updated SRV record is as follows:

;Zone: example.com
