Configure ironic PXE driver for provisioning using IPv6 addressing
==================================================================
The ironic PXE driver operates in either IPv4 or IPv6 mode (IPv4 is the
default). To enable IPv6 mode, set the ``[pxe]/ip_version`` option in the Bare
Metal Service's configuration file (``/etc/ironic/ironic.conf``) to ``6``.
.. Note:: Support for dual mode IPv4 and IPv6 operations is planned for a
future version of ironic.
The PXE drivers operate in such a way that they are able to utilize
both IPv4 and IPv6 addresses based upon the deployment's operating state and
configuration. Internally, the drivers attempt to prepare configuration options for both formats, which allows ports which are IPv6 only to automatically
receieve boot parameters. As a result of this, it is critical that the
``[DEFAULT]my_ipv6`` configuration parameter is set to the conductor's
IPv6 address. This option is unique per conductor, and due to the nature
of automatic address assignment, it cannot be "guessed" by the software.
Provisioning with IPv6 stateless addressing

deprecations:

The ``[pxe]ip_version`` setting has been deprecated and is anticipated to
be removed in the Y* release of OpenStack. This option effectively has had
no operational impact since the Ussuri release of OpenStack where dual
stack IPv4 and IPv6 support was added to Ironic.
