DNS Record Types

CNAME (Canonical Name): a record that creates an alias from one domain name to another. This kind of record cannot be used with a root domain because the root domain needs the SOA record, and potentially MX and TXT records.

A (Host Address): a file that shows the server's IP address

AAAA (ipv6 Host Address): a file that shows the server's ipv6 address

NS (Name Server): Translates a domain name to an IP address.

TXT (Text): A file with key-value pairs stored as text. These files are used for a few different things: to store configuration information, to prepare the domain for the Let's Encrypt DNS-01 challenge, or setting up a domain to use a specific email provider.

ALIAS (Auto resolved alias)

Like a CNAME record because it points one domain name to another. Unlike a CNAME record because other records can be connected to the domain. To Do: MX (Mail eXchange), PTR (Pointer), SOA
