Wildcard DNS (pros and cons)

[JimH@Nucleus.com]

Is there an ability to disallow wildcard DNS?  Lets say I am being a 
seconday DNS server for a customer, and I dont want wildcard DNS 
capabilities, is there a config option to disallow it?   The customers I had 
doing this had no idea what it was they were doing.  It was made so they do 
not have to do any DNS Changes.  they had a website setup so they if their 
customer entired some info, they could create a webpage with 
<subdomain>.theirtld.com domain, and he did not want to do DNS for at all 
(taking the lazy man's approach)



Thanks
