# IPv6
By default, most Openstack services are bound to 0.0.0.0
and service endpoints are registered as IPv4 addresses.
A new variable was created to control this behavior, and to
allow for operation over IPv6 instead of IPv4.
For this, add the following to `local.conf`:
SERVICE_IP_VERSION=6
When set to "6" devstack services will open listen sockets on ::
and service endpoints will be registered using HOST_IPV6 as the
address. The default value for this setting is `4`. Dual-mode
support, for example `4+6` is not currently supported.

``HOST_IPV6`` is normally detected on the first run of ``stack.sh`` but
will not be set if there is no IPv6 address on the default Ethernet interface.
