As far as I've seen, if you don't specify an interface to listen to,
it's going to listen everywhere. But the chances are that it only
listens to interfaces that are already up when it starts. That seems
to be the case for all manner of services.
It's generally held that a server should be up 24/7 in a constant
state. I remember having this kind of problem when I was on dial-up,
which was always going to be sporadic. So many things did not handle
having an interface go down. I had to have a post dial-up rule to
restart NTP, for instance.
