There are many different types of DNS record, according to the way you want to use it. If you use Gandi's LiveDNS, here is the list of DNS registrations that you can add to your domain name: A — Used to point your domain name to a server with a static IPv4 address AAAA — Used to point your domain name to a static IPv6 address Alias — Used to point your bare domain (that is, without 'www' or other subdomain, also called the "Apex") to a webhost, that is, another domain name (and not an IP address) CAA — Used to provide information to a Certificate Authority during the SSL certificate creation process CDS — Used as a copy of a DNS record CNAME — Used to point a subdomain to another web address DNAME — Used to create a domain alias DS — Used to establish a chain of trust to your DNS zone so that DNSSEC will work LOC — Contains geographic data about your domain MX — Used to define a mail server, that is, to link your domain name to an email service NAPTR — Principally used to manage internet telephony sessions NS — Used to designated the authoritative DNS server PTR — Used to verify the IP address an email is sent from TXT — Used to attach information to your domain or subdomain. Very flexible with many uses, like validating ownership of a domain name in the context of attributing an SSL certificate or adding an SPF record, used to authenticate emails SRV — Used to link a "web" service to a host name (i.e. another domain name) SPF — Formerly used record format for preventing email spoofing. Now replaced with a specifically formatted TXT record RP — Used to provide information about a "Responsible Party" for a domain name SSHFP — Used to identify SSH keys associated with a domain name TLSA — Used to specify certificate constraints for services on a particular TCP or UDP port. At least one TLSA record should provide validation for a certificate All of these DNS records are supported by the Gandi LiveDNS REST API.
