Error querying a.gtld.biz.

[Ryan McCain]

Im going through the O'Reilly BIND book and on pp79-80 it discusses querying your parents servers.  If you see my results below, the TLD DNS (no sure if thats the right terminology) have no idea of our domain. I am under the impression that the state.la.us nameservers don't have our NS's registered.  Is that correct?  If so, does this really matter?

Sorry for the newbie questions.. I can assure you I'm reading and googling trying to figure this out on my own before wasting you guys time.
