Um, did you try the documentation in the BIND distribution? "The
book" only covers through BIND 8.1.2 and the address-sorting features were
added in BIND 8.2, so you'll have to make do with ISC's docs for now.

Sounds like "sortlist" is what you want. But you have to configure each
network in the named.conf file. If I recall correctly, BIND 4 just
*assumed* a network size based on how your local interfaces were
configured. Since that's not always a good assumption, and because
sometimes you may wish to selectively override the behavior, BIND 8 has
you specify all of the networks explicitly.
