In order to use dual-stack, bridges must have a IPv4 address assigned
(can be a dummy one from a privacy range or 127.0.0.0/8).
+
+Let me repeat: dual-stack only works when you assign a primary IPv6 address
+(private or public, doesn't matter) *and* add an additional IPv4 address.
+Yes, the IPv4 address can be a private address, the containers can still
+have a public IPv4 address.
+
+A complete example looks like this:
+
+auto bridge0
+iface bridge0 inet6 static
+ address 2a07:6b47:4::4:1
+ netmask 48
+
+ up ip addr add 127.4.4.1 dev $IFACE
+ down ip addr del 127.4.4.1 dev $IFACE
