DNS (Domain Name System), is the service that changes between Internet names and Internet addresses. Internet names are the stars that we use to refer to hosts on the Internet, such as www.cpanelkb.net. Internet companies are the numbers that routers use to move traffic over the Internet, such as 184.108.40.206
DNS records or Zone reports are used for mapping URLs to IPs. These records are discovered in the DNS server. It relates your website to the outside world. When the URL is copied on the browser it is moving forward to your DNS servers and then gets pointed to webservers.
DNS server configuration file path is /etc/named.conf
Domains DNS zone files available on your cpanel server.

Domains DNS zone records are available on your Cpanel server.
Address Mapping records (A)
Record A specifies the IP address for a given host. Records are applied for the conversion of domain titles to corresponding IP addresses.
example.com. IN A 220.127.116.11
IP Version 6 Address records (AAAA)
The record AAAA (also a Quad-A record) specifies the IPv6 address for a given host. So it operates the same way as the A record and the difference is the type of IP address.
linux aaaa 3ffe:1900:4545:2:02d0:09ff:fef7:6d2c
Canonical Name records (CNAME)
A CNAME record or legal name report makes one domain name an alias of different. The aliased domain gets all the subdomains and DNS records of the sensitive.
mail 14400 IN CNAME domain.com.
www 14400 IN CNAME domain.com.
Mail exchanger record (MX)
The MX history shows that all emails @ mydomain.com should be routed to the mail server at mydomain.com. The DNS record proves that mydomain.com is placed at 18.104.22.168. This proposes that emails meant for firstname.lastname@example.org will be routed to the email server at 22.214.171.124. This completes the task of the MX record. The email server on that server then takes over, gets the email, and then moves to distribute it to the user “test”.
mydomain.com. 14400 IN MX 0 mydomain.com.
Name Server records (NS)
An NS record or name server record maps a domain name to a list of DNS servers authorized for that domain. Organizations depend on NS records.
NS Record Name Server Record which symbolizes the Authoritative Name Servers for a particular Domain. It should need at least two nameservers.
example.com. IN NS ns1.nameserver.com.
example.com. IN NS ns2.nameserver.com.
Reverse-lookup Pointer records (PTR)
As exposed to deliver DNS determination (A and AAAA DNS records), the PTR record is used to mark up domain names based on an IP address.
Start of Authority records (SOA)
The record defines core data about a DNS zone, including the basic name server, the email of the domain administrator, the domain serial number, and several timers relating to restoring the zone.
Text records (TXT)
The TXT reports are custom records that contain machine-readable data. The record is applied by Sender Policy Framework (SPF) to prevent fake emails to appear being sent by you.
