DNS Lookup Tool

The DNS lookup tool helps you inspect the records that power a domain. It is useful when setting up websites, email hosting, SSL, domain connections, and troubleshooting DNS issues.

This tool now performs a live DNS lookup using your server's PHP DNS functions.

Common DNS Records

A Record

Connects a domain name to an IPv4 address and is commonly used to point a domain to a web server.

MX Record

Specifies the mail server that should receive email for a domain.

TXT Record

Used for verification, email protection, SPF, DKIM, and other text-based domain settings.

CNAME Record

Points one hostname to another hostname and is commonly used for aliases.

NS Record

Defines which name servers are authoritative for a domain.

AAAA Record

Maps a hostname to an IPv6 address.

Why DNS Lookup Matters

DNS records affect where your website loads from, where your emails are delivered, and how services verify your domain. DNS lookup is especially useful when troubleshooting email delivery, domain verification, hosting migrations, website downtime, and SSL configuration.
