-IPv4/IPv6 Dual Stack Mode
--------------------------
-
-If you want to run in an IPv4/IPv6 dual stack mode and want to define your public and/or
-cluster networks, then you need to specify both your IPv4 and IPv6 networks for each:
-
-.. code-block:: ini
-
-	[global]
-		# ... elided configuration
-		public_network = {IPv4 public-network/netmask}, {IPv6 public-network/netmask}
-
-This is so that Ceph can find a valid IP address for both address families.
-
-If you want just an IPv4 or an IPv6 stack environment, then make sure you set the `ms bind`
-options correctly.
-
-.. note::
-   Binding to IPv4 is enabled by default, so if you just add the option to bind to IPv6
-   you'll actually put yourself into dual stack mode. If you want just IPv6, then disable IPv4 and
-   enable IPv6. See `Bind`_ below.
