## Synopsis

- Manage DNS resolver on a BIG-IP.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---

answer_default_zones
boolean

Choices:
- no
- yes

Specifies whether the system answers DNS queries for the default zones localhost, reverse 127.0.0.1 and ::1, and AS112.
When creating a new resolver, if this parameter is not specified, the default is `no`, meaning that the system passes along the DNS queries for the default zones.

cache_size integer |  | Specifies the size of the internal DNS resolver cache. When creating a new resolver, if this parameter is not specified, the default is 5767168 bytes. After the cache reaches this size, when new or refreshed content arrives, the system removes expired and older content and caches the new or updated content.
name string / required |  | Specifies the name of the DNS resolver.
partition string | Default: "Common" | Device partition to manage resources on.
provider dictionary added in 2.5 |  | A dict object containing connection details.
| auth_provider string |  | Configures the auth provider for to obtain authentication tokens from the remote device. This option is really used when working with BIG-IQ devices.
| password string / required |  | The password for the user account used to connect to the BIG-IP. You may omit this option by setting the environment variable `F5_PASSWORD`. aliases: pass, pwd
| server string / required |  | The BIG-IP host. You may omit this option by setting the environment variable `F5_SERVER`.
| server_port integer | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
| ssh_keyfile path |  | Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable `ANSIBLE_NET_SSH_KEYFILE`.
| timeout integer |  | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.

transport
string

Choices:
- cli
- rest ←

Configures the transport connection to use when connecting to the remote device.

| user string / required |  | The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You may omit this option by setting the environment variable `F5_USER`.

validate_certs
boolean

Choices:
- no
- yes ←

If `no`, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.
You may omit this option by setting the environment variable `F5_VALIDATE_CERTS`.

randomize_query_case
boolean

Choices:
- no
- yes

When `yes`, specifies that the internal DNS resolver randomizes character case in domain name queries issued to the root DNS servers.
When creating a new resolver, if this parameter is not specified, the default is `yes`.

route_domain integer |  | Specifies the route domain the resolver uses for outbound traffic.

state
string

Choices:
- present ←
- absent

When `present`, ensures that the resource exists.
When `absent`, ensures the resource is removed.

use_ipv4
boolean

Choices:
- no
- yes

Specifies whether the system can use IPv4 to query backend nameservers.
An IPv4 Self IP and default route must be available for these queries to work successfully.
When creating a new resolver, if this parameter is not specified, the default is `yes`.

use_ipv6
boolean

Choices:
- no
- yes

Specifies whether the system can use IPv6 to query backend nameservers.
An IPv6 Self IP and default route must be available for these queries to work successfully.
When creating a new resolver, if this parameter is not specified, the default is `yes`.

use_tcp
boolean

Choices:
- no
- yes

Specifies whether the system answers and issues TCP-formatted queries.
When creating a new resolver, if this parameter is not specified, the default is `yes`.

use_udp
boolean

Choices:
- no
- yes

Specifies whether the system answers and issues UDP-formatted queries.
When creating a new resolver, if this parameter is not specified, the default is `yes`.

## Notes

Note

- For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
- Requires BIG-IP software version >= 12.
- The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.

## Examples

    - name: Create a simple DNS responder for OCSP stapling
      bigip_dns_resolver:
        name: resolver1
        provider:
          password: secret
          server: lb.mydomain.com
          user: admin
      delegate_to: localhost
