named periodically scans the interface list, and enables listening for
queries and responses on the interfaces it finds, and disables listening on
interfaces that have disappeared since the last time it checked.  When you
bring the PPP line up, it won't start listening for responses on that
interface until it next scans the interface list and enables it.

The scan period is configurable with the "interface-interval" option, and
defaults to 1 hour.
