module: cloudscale_floating_ip
short_description: Manages floating IPs on the cloudscale.ch IaaS service
description:
- Create, assign and delete floating IPs on the cloudscale.ch IaaS service.
notes:
- To create a new floating IP at least the C(ip_version) and C(server) options are required.
- Once a floating_ip is created all parameters except C(server) are read-only.
- It's not possible to request a floating IP without associating it with a server at the same time.
- This module requires the ipaddress python library. This library is included in Python since version 3.3. It is available as a
module on PyPI for earlier versions.

options:
state:
description:
- State of the floating IP.
default: present
choices: [ present, absent ]
type: str
ip:
description:
- Floating IP address to change.
- Required to assign the IP to a different server or if I(state) is absent.
aliases: [ network ]
type: str
ip_version:
description:
- IP protocol version of the floating IP.
choices: [ 4, 6 ]
type: int
server:
description:
- UUID of the server assigned to this floating IP.
- Required unless I(state) is absent.
type: str
type:
description:
- The type of the floating IP.
choices: [ regional, global ]
type: str
default: regional
region:
description:
- Region in which the floating IP resides (e.g. C(lgp) or C(rma)).
If omitted, the region of the project default zone is used.
This parameter must be omitted if I(type) is set to C(global).
type: str
prefix_length:
description:
- Only valid if I(ip_version) is 6.
- Prefix length for the IPv6 network. Currently only a prefix of /56 can be requested. If no I(prefix_length) is present, a
single address is created.
choices: [ 56 ]
type: int
reverse_ptr:
description:
- Reverse PTR entry for this address.
- You cannot set a reverse PTR entry for IPv6 floating networks. Reverse PTR entries are only allowed for single addresses.
type: str
