The O'Reilly book _DNS and BIND_ says:

[QUOTE]
10.4.3.2 Interface interval

We've said already that BIND, by default, listens on all of a host's network interfaces. BIND 8 is actually smart enough to notice when a network interface on the host it's running on comes up or goes down. To do this, it periodically scans the host's network interfaces. This happens once each interface interval, which is 60 minutes by default. If you know the host your name server runs on has no dynamic network interfaces, you can disable scanning for new interfaces by setting the interface interval to zero to avoid unnecessary hourly overhead:

options {
                interface-interval 0;
};
On the other hand, if your host brings up or tears down network interfaces more often than every hour, you may want to reduce the interval.

But when I tried it, named noticed right away that I had brought up an interface. Will investigate further.
