--bind-dynamic
Enable a network mode which is a hybrid between
--bind-interfaces
and the default. Dnsmasq binds the address of individual interfaces,
allowing multiple dnsmasq instances, but if new interfaces or
addresses appear, it automatically listens on those (subject to any
access-control configuration). This makes dynamically created
interfaces work in the same way as the default. Implementing this
option requires non-standard networking APIs and it is only available
under Linux. On other platforms it falls-back to --bind-interfaces mode.
