Choosing DNS record types

Domain Name Systems (DNS) use different record types for different purposes.
This article helps you determine which record type you should use when creating
a DNS record in the Cloud Control Panel.

A or AAAA

Type A is an IPv4 address record. Type AAAA is an IPv6 Address record, so use this
record type if your server has an IPv6 address as a target.

Use an A or AAAA record to point to an IP address. In simple cases, you might
have a single A or AAAA record as your base record pointing to a single IP
address. Often, there are A or AAAA records that point to different IP addresses.

Note: If you have a base record (not required), it must be an A or AAAA
record. For example, you could have www.mydomain.com as an A record that
points to 1.2.3.4, and www.domain.com might be a CName record that points
to www.myotherimportantdomain.com. Likewise, you might have a
mail.domain.com record pointing to 5.6.7.8.

Canonical name (CName)

Use a CName record to point to another domain name. For example, point
mail.mydomain.com to mydomain.com.

Mail exchange (MX)

Use an MX record for mail delivery. For example, creating an MX record for
domain.com enables you to set up an email address like
mailto:[email protected].

Name server (NS)

Use an NS record to delegate an authoritative DNS server for a domain or
subdomain.

Server locator record (SLR)

Use an SLR to assign a host and port for certain services, such as a Lightweight
Directory Access Protocol (LDAP), for a domain.

Text (TXT)

Use a TXT record to store data types, such as Sender Policy Framework (SPF) or
DomainKeys Identified Mail (DKIM) records.
