FAQ ALERT.


The fifth number is no longer the default TTL or the minimum TTL.  It
is the TTL for "negative caching" [q.v.].  BEFORE the SOA, you should
insert:
	$TTL		86400
to preserve your old default TTL.


FAQ ALERT.

The ";" comments are still all that is allowed in the zone files.  The
zone file syntax has not massively changed.  The named.conf syntax has
[hence the name change as well].  That is where you can use /*...*/ and
//... and #... comments.
