Do a non-recursive query (add a "+norec" flag to dig's command-line
arguments) against the parent server if you want to see the referral
information for a delegated subzone. If you do a recursive query, then
the query will in most cases be answered by the child nameserver(s),
which will tend to return unhelpful responses like SERVFAIL if the zone
is not set up on it/them.
