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.


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 as an A record that
points to, and might be a CName record that points
to Likewise, you might have a record pointing to

Canonical name (CName)

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

Mail exchange (MX)

Use an MX record for mail delivery. For example, creating an MX record for 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

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.
