What Are DNS Records?

DNS (Domain Name System) records are the backbone of the internet. They translate human-readable domain names like example.com into machine-readable IP addresses that computers use to communicate. Without DNS, you would need to memorize long strings of numbers to visit any website.

Every domain has a set of DNS records that control how traffic is routed, where email is delivered, and how the domain's ownership is verified by third-party services. Understanding your DNS records is essential for maintaining a healthy web presence.

Common DNS Record Types

Type Description
A Maps a domain to an IPv4 address. The most fundamental DNS record — it tells browsers which server hosts your website.
AAAA Maps a domain to an IPv6 address. The next-generation equivalent of the A record for the newer IP protocol.
MX Mail Exchange record. Directs email to the correct mail server with priority values for failover.
NS Nameserver record. Specifies which DNS servers are authoritative for the domain.
TXT Text record. Used for domain verification (Google, Microsoft), SPF email authentication, DKIM signatures, and DMARC policies.
CNAME Canonical Name record. Creates an alias that points one domain name to another, commonly used for subdomains and CDNs.
SOA Start of Authority record. Contains administrative information about the zone, including the primary nameserver, admin email, and refresh intervals.

When to Use DNS Lookup

Troubleshooting: If your website isn't loading or email isn't being delivered, a DNS lookup can reveal misconfigured records, wrong IP addresses, or missing MX entries that are causing the issue.

Migration: When moving to a new hosting provider or email service, use DNS lookup to verify that your records have propagated correctly and point to the right servers.

Verification: Many services (Google Workspace, SSL providers, CDNs) require you to add specific TXT or CNAME records. Use this tool to confirm they are in place before proceeding.

Security audits: Check that your SPF, DKIM, and DMARC records are properly configured to prevent email spoofing and phishing attacks targeting your domain.
