What is a DNS Record?

DNS (Domain Name System) records map human-readable domain names to machine-readable addresses and other data. Every domain on the internet relies on DNS to function.

When you visit a website, your browser performs a DNS lookup to translate the domain (e.g., example.com) into an IP address that servers can understand.

Common DNS Record Types

AMaps a domain to an IPv4 address
AAAAMaps a domain to an IPv6 address
MXSpecifies mail servers for the domain
TXTStores text data (SPF, DKIM, domain verification)
CNAMEAlias pointing to another domain name
NSIdentifies the authoritative name servers

Common Use Cases

Domain Verification

Confirm TXT records for Google Search Console, domain ownership proofs, or SPF/DKIM email authentication.

Email Troubleshooting

Check MX records to diagnose email delivery issues and verify mail server configuration.

DNS Propagation

Verify whether updated DNS records have propagated by checking the current values returned by Cloudflare DNS.

Security Audits

Inspect NS records to identify the hosting provider and validate authoritative name server configuration.

CDN Configuration

Verify CNAME records pointing to CDN providers like Cloudflare, Fastly, or AWS CloudFront.

Reverse DNS Lookup

Use PTR records to resolve an IP address back to its associated hostname for network diagnostics.
