We could not skip one of the essentials – the DNS CNAME record- to expand the information about Domain Name System records. So let’s dive in and explain a little bit more about it.
DNS CNAME record explained
Another way that the DNS CNAME record is also known as the canonical name record. It has a very specific role. Which is to define one domain name is just a different way to receive the primary hostname. This host name is also known as the canonical domain. Through you are able to benefit from the CNAME record. You can use it for different results and many purposes, but the appropriate way of applying it is for subdomains.
Simply directing your subdomains to your primary domain is the perfect case of using the CNAME record.
There is one thing that you should remember for the DNS CNAME record. If you have such a record already created for one hostname, it will not give you the chance to import any other DNS records for that specific hostname. If you desire to have an action similar to this, directing one hostname to another but also adding more records, such as MX records, you can use the ALIAS record. And that will help you achieve this goal.
