DNS structure for a multi-servers

Hi,
I have Number of different servers that working on different technologies
CentOS + DirectAdmin servers as VPS for resellers (reseller per server)
CentOS + DirectAdmin servers for shared hosting customers
Windows hosting servers, application servers, and more...

I want to create a more efficient DNS management, if possible between all servers and at least among all the DirectAdmin servers

for example, every server can manage is domains records, but the NS will be the same (or can be the same) in all directadmin servers

I have also 3 separate areas for the servers
Data-center in Israel
2 Data-centers in USA
and Additional Data-center in Europe.

Would love to hear your learned advice,
Star Network.

For DirectAdmin it's quite simple actually; you can use the DirectAdmin Multi Server Setup.

Are you managing DNS for the Windows based servers on Windows? If so you'll need to learn how Windows can notify other (non-Windows) servers of changes to slave zones; I don't know, and it's really beyond the scope of DirectAdmin forums.
