No idea about this one.  The right answer is provided by the
authoritative name servers and the web server there is giving
the expected data.

You may have some wrong data cached somewhere -- but the info
above is not sufficient to diagnose it.

This one is different.  The name servers for ocmelbourne.com are
ns1.olchosting.net and ns2.olchosting.net and both of them give
NXDOMAIN responses to an A query for www.ocmelbourne.com -- so
there's just no way that name is going to work.

It looks more likely that your network has an internal problem.
