named will periodically scan the system's interface list to see if any
new interfaces need to be listened-upon, or if it should stop trying to
listen on interfaces that have gone away. The frequency of this periodic
scan is controlled by the "interface_interval" option. You could, I
suppose, tune that to be very rabid about scanning interfaces, but you
might waste nameserver resources that way.
A possible alternative would be to incorporate an rndc command (I'm
assuming you're running BIND 9 here) into your PPP server startup
script(s). A "reload" would force an immediate interface-scan, I think
even a "reconfig" (which is less intrustive) would be sufficient to
trigger a scan...
