A-records

An A-record is used to send traffic from a domain or subdomain to an IP address.

AAAA-records

An AAAA-record points a domain or subdomain, to an IPv6 address. The AAAA-record is similar to the A-record, but instead of pointing to an IPv4 address, it points to an IPv6 address.

CNAME

A CNAME (Canonical name) is a record used to specify a domain name as an alias for another domain.

TXT records

The TXT records are used to insert arbitrary text into a DNS record. These records are not used to direct any traffic. Instead they provide needed information to outside sources. With TXT records you can also add Sender Policy Framework (SPF) data.

SRV records

An SRV record is used to specify the location with a hostname and a port.

TLSA-records

A TLSA-record is used to connect a TLS server certificate, or public key, with the domain name where the record is found.

SSHFP records

SSHFP records contain fingerprints for public keys used for SSH. When a SSH client connects to a server, it checks the corresponding SSHFP record. If the record's fingerprint matches the server's, the server is authenticated and it is safe to connect.

MX records

An MX record is used to add your own mail server, like for example Microsoft Exchange Server. You can also set a value to prioritize mail delivery, if there are several mail servers available.
