Help... DNS Structuring Question!

[Amir]

I'll tell you the situation again , and shortly :
all i want is to elieviate load from the "." root servers and not waste time
by quering "." and ".com" over and over..
how can i make my ns's go straight to .com when the see a query to the .com
domain ?
(not using previosly cached data, that would mean going to the root when the
cache ttl's out)

Stub works for any zones, assuming that the proper connectivity is in place
and
that the authoritative servers allow the stub to query for SOA and NS
records. You
can build a whole DNS infrastructure based on stubs. The ANX (Automotive
Network
eXchange), for instance.
