module: nios_network
author: "Peter Sprygada (@privateip)"
short_description: Configure Infoblox NIOS network object
deprecated:
    why: Please install the infoblox.nios_modules collection and use the corresponding module from it.
    alternative: infoblox.nios_modules.nios_network
    removed_in: 5.0.0
description:
  - Adds and/or removes instances of network objects from
    Infoblox NIOS servers.  This module manages NIOS C(network) objects
    using the Infoblox WAPI interface over REST.
  - Supports both IPV4 and IPV6 internet protocols
requirements:
  - infoblox-client
extends_documentation_fragment:
- community.general.nios

options:
  network:
    description:
      - Specifies the network to add or remove from the system.  The value
        should use CIDR notation.
    required: true
    aliases:
      - name
      - cidr

  options:
    description:
      - Configures the set of DHCP options to be included as part of
        the configured network instance.  This argument accepts a list
        of values (see suboptions).  When configuring suboptions at
        least one of C(name) or C(num) must be specified.
    type: list
    elements: dict
    suboptions:
      name:
        description:
          - The name of the DHCP option to configure. The standard options are
            C(router), C(router-templates), C(domain-name-servers), C(domain-name),
            C(broadcast-address), C(broadcast-address-offset), C(dhcp-lease-time),

          - The value of the DHCP option specified by C(name)
        required: true

        description:
          - Only applies to a subset of options (see NIOS API documentation)
        type: bool
        default: 'yes'

        description:
          - The name of the space this DHCP option is associated to
        default: DHCP
        type: str
  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.
    type: dict
  comment:
    description:
      - Configures a text string comment to be associated with the instance
        of this object.  The provided text string will be configured on the
        object instance.
    type: str
  container:
    description:
      - If set to true it'll create the network container to be added or removed
        from the system.
    type: bool
  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.
