The delegation for zaiqtech.com is messed up. The servers for .com say
it is served by ns2.connactivity.com and connactivity.connactivity.com.
However neither of these servers is authoritative for this zone. Both
of them claim the zone is served by a different set of name servers,
only one of which -- connactivity.connactivity.com -- is listed in the
parent zone. And that server isn't authoritative for it. Complain to
the administrators of both zones. How you do this is left as an
exercise to the reader. :-)
