Put it at the top of each master file. Don't just pick a random number
either; this controls the default TTL for each record in the zone. If you
used 1234567, for example, it might take more than 2 weeks for a change to
propagate to all caching servers.

Why would you want to expire a zone in less than 7 days?

If you have any names with underscores in them, BIND 8 will complain
bitterly about them. But you can shut it up with the check-names option if
you wish.
