  First of all Rick there are 13 Root servers. A thru M.

  If you want that list I will be happy to provide it.  Just let me know.

  You have this a bit backwards.  Name servers are the starting point.
Those Name servers "Zone files" are provided through a number of sources,
but one of those sources in NSI.  In that Zone file, under the current structure

contain all the "Official" Domains that are available at that point in time.
Now, you can add or modify that Zone file to include additional Domains
or tLD's or even gTLD's should you so choose.  But at that point those
additional DN's for those "Additional" TLD's or gTLD's are than only resolvable
from that particular Name Server or any other Name server that contains
the exact same information that that "Zone file" has been loaded onto.

  This is essentially correct.  But it shouldn't be.

  Literally, .COM.NET and .COM.AU are neither Domains.  Do a whois on
them yourself and you see that they are "Not Found".  Now .AU is a ccTLD,
any DN that is registered in the TLD should be resolvable all the way back
to the Root or "." (Any of the 13 "Sanctioned" legacy Root servers, A-M)
