The following series of articles details information of DNS Records, we are covering each setting in the series, providing basic use and purpose.

What are DNAME Records, what are they used for, and how do they work?

The DNAME Records are known for creating the CNAME Records, which are used for creating an alias for the domains and subdomains. These records avoid the need for creating separate records for other domains that are hosted on the same server but have different addresses.

The main difference between the CNAME and DNAME records is that the former is used for setting the alias for the exact name only. DNAME records, however, allow you to set the alias for the main name, as well as, subnames. The DNAME record allows you to link one domain to another domain. Once you make changes to the A records, it will change the address where the domain is pointing to.

What are DNSKEY Records, what are they used for, and how do they work?

The DNSKEY is defined by RFC 4034 and the records have the same format and structure as the KEY records. These records are known for storing a specific type of key that can be used for the verification of the DNSSEC signature. You are supposed to get the DNSSEC enabled with your current DNS provider in order to activate the DNSKEY.

What are DS Records, what are they used for, and how do they work?

The DNSSEC record will not work until you add the accurate DS records to your current domain. You can get the DS record integrated into your domain through your DNS provider. This record is identified by RFC 4034. The main use of the DS records is to verify the digital signature of the DNS. You can make changes to the DS records from the Order View tab in the control panel.
