DNS server configuration

Configuring DNS is complex enough to fit a single blog post.
It takes a lot of preparations in order to establish all the framework.
So, I'll try to organize what I'll explore by breaking down in further posts.

After DNS server installation, DNS daemon configuration may be necessary.
This is so unless the server will run on an immutable zones (recommended).

As an example I'll be working with the business.corp domain.

Here are the fundamental steps:
   

• Define a DNS internal root and the Internal DNS servers.
  Later on, address the external DNS requirements.
     
  Possible types of root domain "." configuration:
• External (DNS root hints);
• Internal  (DNS internal root).   
        
• Set the DNS loopback zone configuration (recommended);
     
• Define the DNS configuration file;
       
• Define the DNS zone data.
