Creating a DNS Record

All computers that need to be accessed from other DNS domains must have DNS records. Although there are many different types of DNS records, most of these record types are not commonly used. The following is a list of record types in CloudBlue Commerce:

• A (Address) maps a host name to an IP address. For every computer name you see on the internet, there must be an A record linking to an IP address.
• AAAA (IPv6 address) maps a host name to a 128-bit IP address (IPv6 address). This record states that all requests for a hostname will be sent to a server with this IP address.
• CNAME (Canonical Name) sets an alias for a host name. For example, using this record, zeta.tvpress.com can have an alias as www.tvpress.com. The most popular use of the CNAME record type is to provide access to a web server using both the standard www.domain.com and domain.com (without www). This is usually done by creating an A record for the short name (without www), and a CNAME record for the www name pointing to the short name. The CNAME record must always point to the A record to avoid circular references.
• NAPTR (Name Authority Pointer) implements regular expression-based rewrite rules and is used to route internet telephony sessions.

  Important: Creating NAPTR records is only supported for the PowerDNS server.

• MX (Mail Exchange) specifies a mail exchange server for the domain, which allows mail to be delivered to the correct mail servers in the domain. It defines the location of where mail is delivered for the domain.
• The SRV record is a DNS record that provides information on service available at domain.
• NS (Name Server) specifies a name server for the domain, which allows DNS lookups within various zones. It defines an association between a given domain name and the name servers that store information for that domain. One domain can be associated with any number on name servers.
• The TXT (Text) record provides up to 255 characters of free form text to be linked to a domain name. The TXT record may contain any information that the owner wants to be accessible on a DNS server. TXT records linked with domain names are widely used in the Sender Policy Framework (SPF) anti-forgery solution.
• CAA (Certification Authority Authorization) allows domain name owners to indicate to certificate authorities whether they are authorized to issue digital certificates for their domain names.
• TLSA (The DNS-Based Authentication of Named Entities (DANE) / Transport Layer Security (TLS) Protocol) allows domain name owners to associate TLS server certificates with their domain names.

Below is a full description of the operation sequence for adding each DNS record type.

Note: The DNS configurations of disabled domains cannot be managed.
