Supported Record Types
- A - IPv4 address used to map hostnames to an IP address of
- 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 authoritative 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
- 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
- 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.
