Use the `infoblox_zone_delegated` data source to retrieve the following information about a delegated DNS zone from the corresponding object in NIOS:

| **Parameter** | **Description** | **Example** |
| --- | --- | --- |
| `fqdn` | The name of the DNS zone. For a reverse zone, this is in CIDR format.   
For other zones, this is in FQDN format. This value can be in unicode format. | `demozone.authzone.com`<br>For reverse mapping zone: `11.10.0.0/24` |
| `delegate_to` | The remote server to which the NIOS appliance redirects queries for data for the delegated zone. | `name = "test22.dz.ex.com"`  
`address = "10.0.0.1"` |
| `view` | The name of the DNS view in which the zone resides. | `external` |
| `disable` | The flag that determines whether the zone is disabled or not. | `false` |
| `locked` | The flag that restricts other administrators from making any changes.<br>Note that this flag is for administration purposes only. The zone will continue to serve DNS data even when it is locked. | `false` |
| `ns_group` | The name server group that serves DNS for this zone.  
The delegation NS group that is bound to the delegated zone. | `demoGroup` |
| `delegated_ttl` | The TTL value for the delegated zone. | `20` |
| `zone_format` | The field that determines the format of the zone. The valid values are `FORWARD`, `IPV4` and `IPV6`. | `FORWARD` |
| `comment` | A description of the DNS zone. This is a regular comment. | `The delegated zone object in NIOS.` |
| `ext_attrs` | The set of extensible attributes of the DNS view, if any.  
The content is formatted as a string of JSON map. | `{\"Location\":\"unknown\",\"TestEA\":\"ZoneTesting\"}` |

To retrieve information about delegated zones that match the specified filters, use the `filters` argument and specify the parameters mentioned in the below table. These are the searchable parameters of the corresponding object in Infoblox NIOS WAPI. If you do not specify any parameter, the data source retrieves information about all delegated zones in the NIOS Grid.

The following table describes the parameters you can define in the `infoblox_zone_delegated` data source block:

| **Parameter** | **Description** |
| --- | --- |
| `view` | Specifies the name of the DNS view in which the DNS zone exists.  
If a value is not specified, matching objects are retrieved from all DNS views in the NIOS Grid. |
| `fqdn` | Specifies the name of the DNS zone. |
| `zone_format` | Specifies the format of the DNS zone. |
| `comment` | The description of the DNS zone. |
| Extensible Attributes | Specifies the extensible attributes specified for the DNS zone. You must specify the key/value pair within the `filters` argument.  
Example:  
`filters = {`  
`"*Site" = "some test site"`  
`}` |

## Example of the Zone Delegated Data Source Block

`resource "infoblox_zone_delegated" "zone_delegate_to" {`  
`    fqdn = "zone_delegate.test_fwzone"`  
`    delegate_to {`  
`    name = "test22.dz.ex.com"`  
`    address = "10.0.0.1"`  
`    }`  
`    delegate_to {`  
`    name = "test2.dz.ex.com"`  
`    address = "10.0.0.2"`  
`    }`  
`}`

  
`// accessing Zone delegated by specifying fqdn and view`  
`data "infoblox_zone_delegated" "data_zone_delegated" {`  
`    filters = {`  
`    fqdn = "zone_delegate.test_fwzone"`  
`    view = "default"`  
`    }`  
`// This is just to ensure that the record has been be created`  
`    depends_on = [infoblox_zone_delegated.zone_delegate_to]`  
`}`  
  
`// returns matching Zone delegated with fqdn and view, if any`  
`    output "zone_delegated_data3" {`  
`    value = data.infoblox_zone_delegated.data_zone_delegated`  
`}`
