Generic Zone File??

[Joe]

Thanks, but I should have been more specific.  They want a ZERO maintenance 
DNS server. So that everyone of their customers that registers a domain and 
uses their DNS servers, it would resolve out to their web server.  IE,  no 
zone files, and no entries in named.conf. 

I have scripts that will automate the process, generate zone files, add the 
entry to the conf file and HUP named, but they are wanting the ZERO 
maintenance. 

Thanks again,

Joe
