[Unbound-users] interface-automatic: yes and default listen addresses

Hi Paul,

The option overrides the interfaces specified by the user.  The socket
options that it is using need to use the ANY interface.   It even
detects newly added network interfaces real-time and services them.

Also, the socket options may require IPv6.  I am not sure to what
extent.  Because of that, it may not be such a nice default-option...

Really, it is mostly useful for anycast (load-balancing solutions).

Is what you need an new option that I would call;
set-interface-automatic-if-ANY-is-specified-as-interface ?

Best regards,
   Wouter
