The various sections of the DNS zone ﬁle are responsible from routing to websites, to powering email and establishing security standards for the domain. Each DNS host has a different layout to their DNS zone ﬁles, but essentially the layout for each record consists of 4 columns:
Type: What kind of record. There are currently 48+ record types.
Name: The keyword associated with the record, usually one “level” above the domain name.
Example: If the Name of a Cname record for VBMng.com is “awesome” then this translates to “ awesome.VBmng.com”. This is commonly called a “subdomain”.
Value: The address or primary text input for the record.
Example: The value for ZoomInfo’s “awesome” Cname is “www.example.com”. The “www.example.com” is used as the address you want users directed to when they type awesome.vbmng.com. Therefore, when someone types “awesome.vbmng.com” it will redirect to “www.example.com”.
TTL: Time to live. A record that recommends to other systems how long to cache the DNS value before rechecking.
