DNS problem with standard and wildcard record

I have a domain which I run two LAMP servers for.

One is a standard server and the other is
a * server.

I have two local DNS servers and two public DNS servers.
Both are configured the same way other than the public/private IP's of course.
Here is a snip of what part of it looks like.

A x.x.x.x
$ORIGIN A x.x.x.x A x.x.x.x A x.x.x.x
* A x.x.x.x A x.x.x.x

Internally, everything works as it should. When we enter, we get the server we are supposed to. When we enter, we get what we are supposed to. This confirms to me that the LAMP server and application are configured correctly since they are responding.

However, from the public, testing from some remote DNS test services, if we enter or, both lead to the server.

And if we enter one of the wildcard domains, say, the tests always fail.

"Nameservers listed at parent: No nameservers found at parent nameserver. Fail"

This happens with or without an A record for the pointing to the wildcard LAMP server.

I'm at a loss and searching is finding nothing so thought I would ask here.

Aw gee... it dawns on me why I get this result and it's normal.
The sub-domain names I am looking for don't actually exist as sub-domain names in DNS, they only exist in the application. Doing a sub-domain test fails because no such domain exist but if I connect from a remote location into my sub-domain server, everything works as it should when using sub-domains.
