for communication with networks outside the cloud, including the
Internet.
.. note::
When creating and updating a floating IP, only consider IPv4 addresses
on both the floating IP port and the internal port the floating IP is
associated with. Additionally, disallow creating floating IPs on networks
without any IPv4 subnets, since these floating IPs could not be allocated
an IPv6 address.
- By default, both administrative and end users can associate floating IP
addresses with projects and instances. You can change user permissions for
managing IP addresses by updating the ``/etc/nova/policy.json``
