Previous section: Rackspace Cloud DNS available features
Implementation of Rackspace Cloud DNS is available through our RESTful API. To use our API, you should have a general understanding of Domain Name Systems (DNS) management and be familiar with the following elements:
- RESTful web services
- JSON or XML data serialization formats
For the full list and technical details of all available Cloud DNS API operations, see the Cloud DNS API reference.
Currently available domain and record operations include those shown in the following chart:

The Cloud DNS API service provides support for Name Server (NS), TXT and SRV records. The following detailed information describes each of these record types:
- NS records indicate where the domain’s DNS hosting services are located. They effectively delegate a domain to use a set of name servers.
- TXT records are used primarily for Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records. An SPF record allows administrators to specify which hosts are allowed to send email from a domain by creating a specific SPF record in the public DNS. Mail exchangers then use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain’s administrators. DKIM records are used to associate a domain name to an email to allow an organization to take responsibility for a message in a way that can be validated by a recipient.
- SRV records are used to define the location (hostname and port) of servers used for a specific service.
