What happens to a bound socket when the local IP address it was bound to
becomes invalid?

I.e.: I have a dialup connection with dynamic IP assigned. At least once a
day this drops (grr, don't ask) and comes back up with a different IP assigned.

This makes ntpd very unhappy, as it can't reach the remote servers anymore.
As a workaround I'm killing and restarting ntpd in my ip-up script, but I'm
wondering what the real solution would be.
