+short_description: Manage DNS profiles on a BIG-IP
+description:
+  - Manage DNS profiles on a BIG-IP. There are a variety of DNS profiles, each with their
+    own adjustments to the standard C(dns) profile. Users of this module should be aware
+    that many of the adjustable knobs have no module default. Instead, the default is
+    assigned by the BIG-IP system itself which, in most cases, is acceptable.
+version_added: 2.6
+options:
+  name:
+    description:
+      - Specifies the name of the DNS profile.
+    required: True
+  parent:
+    description:
+      - Specifies the profile from which this profile inherits settings.
+      - When creating a new profile, if this parameter is not specified, the default
+        is the system-supplied C(dns) profile.
+  enable_dns_express:
+    description:
+      - Specifies whether the DNS Express engine is enabled.
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(yes).
+      - The DNS Express engine receives zone transfers from the authoritative DNS server
+        for the zone. If the C(enable_zone_transfer) setting is also C(yes) on this profile,
+        the DNS Express engine also responds to zone transfer requests made by the nameservers
+        configured as zone transfer clients for the DNS Express zone.
+    type: bool
+  enable_zone_transfer:
+    description:
+      - Specifies whether the system answers zone transfer requests for a DNS zone created
+        on the system.
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(no).
+      - The C(enable_dns_express) and C(enable_zone_transfer) settings on a DNS profile
+        affect how the system responds to zone transfer requests.
+      - When the C(enable_dns_express) and C(enable_zone_transfer) settings are both C(yes),
+        if a zone transfer request matches a DNS Express zone, then DNS Express answers the
+        request.
+      - When the C(enable_dns_express) setting is C(no) and the C(enable_zone_transfer)
+        setting is C(yes), the BIG-IP system processes zone transfer requests based on the
+        last action and answers the request from local BIND or a pool member.
+    type: bool
+  enable_dnssec:
+    description:
+      - Specifies whether the system signs responses with DNSSEC keys and replies to DNSSEC
+        specific queries (e.g., DNSKEY query type).
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(yes).
+    type: bool
+  enable_gtm:
+    description:
+      - Specifies whether the system uses Global Traffic Manager to manage the response.
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(yes).
+    type: bool
+  process_recursion_desired:
+    description:
+      - Specifies whether to process client-side DNS packets with Recursion Desired set in
+        the header.
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(yes).
+      - If set to C(no), processing of the packet is subject to the unhandled-query-action
+        option.
+    type: bool
+  use_local_bind:
+    description:
+      - Specifies whether the system forwards non-wide IP queries to the local BIND server
+        on the BIG-IP system.
+      - For best performance, disable this setting when using a DNS cache.
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(yes).
+    type: bool
+  enable_dns_firewall:
+    description:
+      - Specifies whether DNS firewall capability is enabled.
+      - When creating a new profile, if this parameter is not specified, the default is
+        C(no).
+    type: bool
+  partition:
+    description:
+      - Device partition to manage resources on.
+    default: Common
+  state:
+    description:
+      - When C(present), ensures that the profile exists.
+      - When C(absent), ensures the profile is removed.
+    default: present
+    choices:
+      - present
+      - absent
