Supported Record Types

• A - IPv4 address used to map hostnames to an IP address of the host.
• CNAME (Canonical Name Record) - Points to another hostname that already has an A record associated with it. The CNAME record works like an alias. 
• MX - Used to specify a mail server that is responsible for accepting email messages on behalf of a recipient domain.
• SOA - Specifies authoritive information about a domain, including the primary name server(s), the email of the domain administrator, the domain serial number, and TTL's.
• AAAA - IPv6 address used to map hostnames to an IP address of the host.
• NS (Name Server) - NS records indicate where the domain's DNS hosting services are located. It effectively delegates a domain to use a set of name servers.
• TXT - This is a text record and is used primarily for SPF and DKIM records.

- A SPF (Sender Policy Framework) record allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific SPF record in the public (DNS). Mail exchangers use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain's administrator.

- DomainKeys (DKIM) is a method for associating a domain name to an e-mail, thereby allowing an organization to take responsibility for a message in a way that can be validated by a recipient. 

• SRV - Used to define the location (hostname and port) of servers used for a specific service.
