notes:
|
|
- "It is recommended that plays utilizing this module be run with
|
|
C(serial: 1) to avoid exceeding the API request limit imposed by
|
|
the Rackspace CloudDNS API"
|
|
- To manipulate a C(PTR) record either C(loadbalancer) or C(server) must be
|
|
supplied
|
|
- As of version 1.7, the C(type) field is required and no longer defaults to an C(A) record.
|
|
- C(PTR) record support was added in version 1.7
