How does the DNS Work and How To Edit DNS Records with cPanel

How Can You Manage DNS of Your Domain In cPanel

It is important to know working of DNS First before proceeding.When you register for a domain, the domain registrar provide you a control panel named Domain control panel (it is different from cPanel or any other web hosting control panels).

Here you can specify the name servers of the domain,you can renew the domain name, changes in contact information of the domain and many more. These name servers designated in the domain control panel are the authentic name servers of the domain. In these authoritative name servers, it needs to be a zone file in which the DNS records (like NS,A, CNAME, TXT records ) are added.

For perfect name resolution the NS records should be same as the name servers entered in the domain control panel

Users using our name servers, can easily alter the DNS zone file or DNS records in cPanel. Those who are using exterior or any other third party name servers (eg: CloudFlare services), you need to update the DNS records or zone file there in their DNS management area.

How can we Edit DNS records through cPanel as : cPanel > Domains >Advanced DNS Zone Editor

MX record – MX i.e. "Mail Exchange".helps to specify list of mail exchange servers (mail servers) that need to be used for the domain.

PTR record –PTR is "pointer", which helps to get the CNAME from anIPv4 address.

NS record – The authentic name servers of the domain is specified here.
