I'm trying to set up a DNS structure in which I still haven't figured out how to do it. At my workplace I have a DNS BIND server, and now I am finishing installing ISPCONFIG. I want everything I configure for a subdomain in Ispconfig to propagate without having to configure it in BIND again. As the main server is BIND, in ispconfig should I configure which type of DNS? In ispconfig I will configure only my company's subdomains.
