+6. IPv4 and IPv6 dual-stack
+---------------------------
+
+Examples for /etc/network/interfaces above work for IPv6 too when using correct
+IPv6 addresses and netmasks.
+
+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).
