How to Read DNS Records: A Beginner Guide

Published on December 9, 2025 • DNS Basics

Domain Name System (DNS) records are the instructions that live in authoritative DNS servers and provide information about a domain. Think of them as the contacts in your phone book: they tell the internet where to find your website, where to send your email, and more.

Common DNS Record Types

1. A Address Record

The A Record is the most basic and common type. It maps a domain name (like example.com) directly to an IPv4 address.

example.com. 3600 IN A 93.184.216.34

2. AAAA IPv6 Address Record

Similar to the A record, but for IPv6 addresses. As the internet runs out of IPv4 addresses, AAAA records are becoming increasingly important.

example.com. 3600 IN AAAA 2606:2800:220:1:248:1893:25c8:1946

3. CNAME Canonical Name Record

A CNAME Record maps one domain name to another. It's often used for subdomains. For example, pointing www.example.com to example.com.

www.example.com. 3600 IN CNAME example.com.

Note: You cannot put a CNAME record on the root domain (example.com), only on subdomains.

4. MX Mail Exchange Record

MX Records tell email servers where to deliver emails for your domain. You can have multiple MX records with different priorities.

example.com. 3600 IN MX 10 mail.example.com.

5. TXT Text Record

TXT Records allow you to store text information in DNS. They are heavily used for verification (Google Search Console) and email security (SPF, DKIM, DMARC).

example.com. 3600 IN TXT "v=spf1 include:_spf.google.com ~all"
