I recently setup a server with CentOS 5 32bit, Nginx, MySQL, PHP-FPM and APC. I'm currently working on setting up the bind server correctly. I'm creating my main domain zone and I wanted to know if I'm going to use for example domain.com, and want to use sub.domain.com as my server hostname as well as create my own ns1 and ns2 zones. Do I need to create a whole new zone file or can I simply add sub. ns1. and ns2. as
sub.domain.com. IN A XXX.XXX.XXX.XXX
ns1.domain.com IN A XXX.XXX.XXX.XXX
ns2.domain.com IN A XXX.XXX.XXX.XXX
Or do I need to create another separate zone with sub.domain.com for it to work properly?
