	They had better be, otherwise you won't get registered.

	The gTLD nameservers simply provide hints as to what the IP 
addresses are of the nameservers in question.  Once the NS records 
are cached, remote servers will go directly to those machines for the 
next queries.  If those machines themselves then hand out different 
answers, you've got serious problems.

	This just isn't how things work.

	You're trying to use the DNS for a totally inappropriate 
solution.  Use a proper load-balancing tool for the job.


	Oh, and please don't use garbage return addresses to post here. 
The newsgroup you posted this message to is gatewayed to a mailing 
list, and having this garbage in your address is anti-social and 
makes it more difficult for people to reply to you with the kind of 
information you've requested.
