All ok.
ns11:~ # nslookup -querytype=AAAA xserv.ins.dell.com.
.....
** server can't find xserv.ins.dell.com.: NXDOMAIN
Now even the A queries fail.

Keeps failing until TTL timeout or rndc flushname xserv.ins.dell.com.

Yes, we had this reported last month (for premier.dell.co.uk which
CNAME chains to vandom.ins.dell.com, but the effect is exactly the same).
We reported it to dnsad...@dell.com on 28 June. Deafening silence.
They should be returning "nodata" rather than NXDOMAIN for the AAAA
query, of course.
