Yes, this is possible, but only if one adopts a very technical 
definition of the term "domain", one that is recursive and also applies 
to all subdomains as well. If your ISP hosts, for example, the 
"richland.k12.la.us" zone, then you could define a zone on your internal 
server(s) for a subdomain of that, e.g. "internal.richland.k12.la.us", 
and add whatever entries you want to it, which would not necessarily be 
visible to the outside world (unless you wanted it to be). What you 
can't do, though, is add entries in exactly the same subdomain as what 
is hosted externally, and that's probably what you were looking to do...
