	I'm not aware of any.  Moreover, you haven't provided enough 
information about the client side to really begin to try to answer 
the question.

	The first thing you need to do is to get a better idea of where 
you are today, by analyzing the statistics available from your 
existing nameserver.  Tools like 
<ftp://ftp.shub-internet.org/pub/shub/brad/dns/dnsstats.gz> may be 
able to help.

	Before you can start fixing a problem, you first need to better 
understand what it is that you're trying to fix.
