        prior to configuring zones.
    required: true
    default: default
    aliases:
      - dns_view
  grid_primary:
    description:
      - Configures the grid primary servers for this zone.
    suboptions:

          - The name of the grid secondary server
        required: true
  extattrs:
    description:
      - Allows for the configuration of Extensible Attributes on the
        instance of the object.  This argument accepts a set of key / value
        pairs for configuration.
  comment:
    description:
      - Configures a text string comment to be associated with the instance

  state:
    description:
      - Configures the intended state of the instance of the object on
        the NIOS server.  When this value is set to C(present), the object
        is configured on the device and when this value is set to C(absent)
        the value is removed (if necessary) from the device.
    default: present
