Understanding DNS Records

Published: Monday, January 20, 2020

When you start trying to manage your domain’s DNS for the first time, everything can seem very confusing. I am here to help. They’re not so hard once you get a feel for them. Below are explanations of the more common types.

  • A Records: These are also called Address Records or sometimes called Host Records. A record only resolves to IP addresses. These records point your domain to the IP address of your website or hosting.
  • CNAME Records: CNAME stands for Canonical Name Record. CNAME records only resolves to domains and subdomains. For example, you may have “store.myonlinestore.com” set up as the main record. You can create a CNAME alias “shop” and point it to “store.myonlinestore.com”.
  • MX Records: MX stands for Mail Exchange.  This record specifies which servers you use to deliver mails to (often mail.yourdomainhost.com), transforming [email protected] into a working IP address. MX record resolves to Host Records.
  • TXT Records: TXT just stands for Text. These records do not change anything on your domain, but they can be searched for your domain. These records are commonly used by services such as Google, which will ask you to add a string of characters to a TXT record, so that they can search for the record and verify that you are the domain’s owner/have access to the domain’s DNS records. Another example of a TXT record is an SPF record.
