DNS Record Type

📖 DNS Record Type Reference

A quick guide to help you choose the right record type.

IPv4 Address Maps a domain name to a 32-bit IPv4 address (e.g. 93.184.216.34). The most common DNS record used for websites.

AAAA

IPv6 Address Maps a domain to a 128-bit IPv6 address (e.g. 2606:2800::1). Used for the modern internet protocol.

Mail Exchange Specifies the mail servers responsible for receiving email for a domain. Includes a priority value — lower = preferred.

Name Server Delegates a DNS zone to an authoritative name server. These records point to the servers that hold your domain's DNS records.

TXT

Text Record Stores arbitrary text. Commonly used for domain ownership verification, SPF (email anti-spoofing), DKIM, and DMARC policies.

PTR

Pointer / rDNS Reverse DNS lookup — maps an IP address back to a hostname. Used for email deliverability, network diagnostics, and logging.

CNAME

Canonical Name (Alias) Creates an alias from one domain name to another. The DNS lookup follows the chain until an A/AAAA record is found.

SOA

Start of Authority Contains administrative info about the zone: primary nameserver, admin email, zone serial number, and refresh intervals.

CAA

Certificate Authority Authorization Specifies which Certificate Authorities (CAs) are allowed to issue SSL/TLS certificates for your domain, preventing mis-issuance.
