DNS, or the Domain Name System, translates human readable domain names into the technical information computers need to find your website, deliver your email, and connect to other services tied to your domain. Each type of record within your domain's DNS settings serves a specific, distinct purpose.

What should enterprises know about a Records?
An A record points your domain, or a specific subdomain, directly to a numerical IP address, most commonly determining where your website itself is hosted. When someone types your domain into their browser, the A record tells their computer exactly which server to connect to.
What should enterprises know about cNAME Records?
A CNAME record points one domain or subdomain to another domain name, rather than directly to an IP address. This is commonly used for subdomains that should follow wherever the main domain points, without needing to update the subdomain separately if the underlying IP address ever changes.
What should enterprises know about mX Records?
MX records, short for Mail Exchange, determine which mail servers are responsible for receiving email sent to your domain. A domain can have multiple MX records with different priority values, allowing mail delivery to fall back to a secondary server if the primary one is unavailable.
What should enterprises know about tXT Records?
TXT records store text based information within your domain's DNS settings, commonly used for domain ownership verification with third party services, and for email authentication standards that help prevent your domain from being used in spam or phishing attempts. See Understanding SPF, DKIM and DMARC (Email Authentication) if you are setting up email authentication specifically.
What should enterprises know about other Record Types You May Encounter?
Beyond these four common types, you may occasionally encounter other record types such as NS records, which specify which nameservers are authoritative for your domain, or SRV records, used by some specific services to locate particular resources. These are less commonly edited directly by most domain owners compared to A, CNAME, MX, and TXT records.
