Reverse DNS operations#

Use the reverse DNS API operations to view and manage the PTR records associated with a Rackspace cloud device.

Update PTR records#

PUT /v1.0/{account}/rdns

Updates one or more PTR records associated with a Rackspace Cloud device.

Note

This call returns an asynchronous response. Refer to Synchronous and asynchronous responses for more details and examples of the way that asynchronous responses work.

Note

The IP address (data) for a PTR record cannot be modified. To change the reverse DNS for a domain, any existing PTR record(s) must be deleted and new ones created.

Notice in the requests below that the service and device resource URI are specified respectively as the rel and href attributes of the link element.

This table shows the possible response codes for this operation:

Add PTR records#

POST /v1.0/{account}/rdns

Adds one or more PTR record records for a specified Cloud device.

Note

This call returns an asynchronous response. Refer to Synchronous and asynchronous responses for more details and examples of the way that asynchronous responses work.

Note

PTR records can only be added for Rackspace Cloud Servers and Load Balancers.
The id for the record must not be specified.
For First Generation Cloud Servers, when the server is created, each public IPv4 address that comes with the server usually has a default PTR record already created for it. A request to list the PTR records associated with the server should return any PTR records for the server. If a default PTR record exists, the default PTR record can be appropriately modified or deleted and an appropriate PTR record created.

If an attempt to add a PTR record for the public IP address of a newly created First Generation Cloud Server results in a 400 Bad Request error message, that is an indication that a default PTR record for the IP address already exists.
Adding PTR records for IPv6 addresses is supported only for Cloud Servers.

Notice in the requests below that the service and device resource URI are specified respectively as the rel and href attributes of the link element, as follows:

rel – this is the name of the service (as provided in the serviceCatalog from Identity) from where the device was created.
href – this is the URL to the device for which the PTR record is associated. It was returned when the device was created and it uniquely identifies the device.
content – this is currently a place holder for possible future use.

This table shows the possible response codes for this operation:

Response Code	Name	Description
200	Success	Request succeeded.
400	Bad Request	The request is missing one or more elements, or the values of some elements are invalid.
400 500	dnsFault	The DNS service has experienced a fault.
401	Unauthorized	You are not authorized to complete this operation. This error can occur if the request is submitted with an invalid authentication token.
404	Not Found	The requested item was not found.
413	Over Limit	The number of items returned is above the allowed limit.
503	Service Unavailable	The service is not available.

Request#

This table shows the header parameters for the request:

Name	Type	Description
X-Auth-Token	String	Arbitrary character string generated by the authentication service in response to valid credentials.

This table shows the URI parameters for the request:

{account}	String	The tenant ID.

This operation does not accept a request body.
