About DNS record types
A / AAAA
Maps a domain name to an IPv4 (A) or IPv6 (AAAA) address. These are the most common records, used to point your domain to a web server.
MX
Mail exchanger records specify which servers handle email for your domain, listed by priority. Lower numbers are tried first.
TXT
Text records hold arbitrary data. Commonly used for SPF (email authentication), DMARC policies, domain verification tokens, and DKIM public keys.
CNAME
Canonical name records alias one hostname to another. Often used to point subdomains to external services.
NS
Nameserver records delegate authority for your domain to specific DNS servers. Changing these transfers DNS control.
SOA
Start of Authority contains administrative information: primary nameserver, admin contact, and zone serial number used for replication.
CAA
Certification Authority Authorization restricts which certificate authorities can issue SSL certificates for your domain.
SRV
Service records define hostname and port for specific services like SIP, XMPP, or Microsoft services, including priority and weight.
