If your PPP connection is not up, the IP address is not in effect, and
'named' will not bind to it.

This is also a problem for anyone outside your LAN trying to reach you.
If your only name server is only available when YOU dial in, then it
can't be reached by other people when THEY want to find you - e.g., to
return e-mail.  You need a full-time slave server.
