Your websites DNS settings are critical to the basic functions of your domain name. If you have a mistake in your DNS then it’s likely your domain name will appear offline or some users might be able to connect to your website whilst others might not. Generally speaking, your DNS will have at minimum A records, www records and NS records.
If you are using a GUI like cPanel then WHM has many DNS functions in the interface making it easy to edit the DNS Zone file for a domain name. The DNS zone file holds all of the DNS information for a domain name server-side. The DNS zone file for each domain name is usually located in the /var/named folder and will be called domain.db.
