this is the proper and expected response, since the extensus.nl domain is
delegated to servers that don't know about it.
But... I think I found it:
----------
root@ns1:/etc/bind/domeinen# rndc flushtree extensus.nl
root@ns1:/usr/local/sbin# nslookup extensus.nl localhost
;; Got SERVFAIL reply from ::1, trying next server
Server: localhost
Address: 127.0.0.1#53
** server can't find extensus.nl: SERVFAIL
root@ns1:/usr/local/sbin#
----------
this is in fact the same result, using the obsolete "nslookup" command
see the SERVFAIL in dig output above.

Dig does something else then nslookup.
they do mostly the same. However, nslookup does many things that can confuse
users and therefore it's not recommended for diagnosing DNS problems.
Nslookup gave response before the "rndc flushtree", dig did not.
it did, you just didn't see it. See above, it returned SERVFAIL.
