Here's one way to do an endless set of lookups.  If you have a list of
names and/or IP addresses in "namelist.txt": 
--
#!/bin/sh

while true
do
  for name in `cat namelist.txt`
  do
    nslookup $name
  done
done

The Net::DNS module for Perl is also very useful for scripting this kind
of task.  

A Google search brought up www.dnsstuff.com and www.dnsreport.com which
could also help measure your server response under load.
