There is an integral part of the Internet, called the DNS or Domain Name System which helps in converting human-readable domain names, like example.com into computer-readable IP addresses, like 192.0.32.10. The zone files residing on one’s server is used by DNS in converting the domain names into IP addresses.

You can find innumerable types of records inside a domain’s zone file. It also allows in creating and deleting A and CNAME (Canonical Name) records. Note that a record’s time cannot be set to live (TTL) in this interface. Records created with the help of this interface defaults to the TTL. In order to set the TTL for a record, you can use cPanel’s Advanced Zone Editor interface (cPanel >> Home >> Domains >> Advanced Zone Editor). One can read our cPanel Deprecation Plan documentation to get more vivid details on this topic.

Add an A Record

The ‘A’ record is a DNS record that converts the hostname into IP address, that is from a human-readable component to a computer-readable component. There are steps to add this A record.

Steps:

  • Select a specific domain preferred to manage from the Domain menu, in case this account has more than one domain.
  • Then you need to enter the Name and Address of the A record accordingly.
  • Lastly, click on Add A Record.

Add A CNAME Record

The CNAME record helps in creating a handle for a different domain name that is looked after by the DNS. There are steps to add this CNAME record.

Steps:

  • Select a specific domain preferred to manage from the Domain menu, in case this account has more than one domain.
  • Then in the Name and CNAME text box, enter the CNAME record.

Delete A Record

Steps:

  • Select a specific domain preferred to manage from the Domain menu, in case this account has more than one domain.
  • Click on the Delete link available beside the record option and finally click on the Delete option. The record is hence deleted.

DNSSEC

DNS Security Extensions (DNSSEC) help in adding an extra sheets of security to the domains’ DNS records. It uses digital signatures (protecting clients from deadly Spoofing or Man-in-the-middle attacks) and cryptographic keys in validating DNS responses to be authentic.

Enable DNSSEC

Steps:

  • Select a specific domain preferred to manage from the Domain menu, in case this account has more than one domain.
  • Click on Enable. The system will initiate a new DNSSEC key, and accordingly a new line will appear with these information like: Key Tag (An integer value identifying the domain’s DNSSEC record, Algorithm (The record’s encrypted signature), Digest Type (The algorithm type constructing the digest and selecting the Digest Type supported by the registrar) and Digest (An alpha-numeric string initiated by the algorithm.

Disable DNSSEC

Steps:

  • Select a specific domain preferred to manage from the Domain menu, in case this account has more than one domain.
  • Click on Disable option.
