DNS Lookup Tool β How to Use & Why It Matters
DNS (Domain Name System) translates human-readable domain names (like google.com) into IP addresses that servers use. Our DNS Lookup tool queries multiple record types instantly β no software required.
What is an A record?
An A record maps a domain to an IPv4 address. It's the most basic DNS record β it tells browsers which server to connect to.
What is an MX record?
MX (Mail Exchanger) records specify which mail servers handle email for a domain. Essential for email delivery troubleshooting.
What is a TXT record?
TXT records store text data. Commonly used for SPF (spam prevention), DKIM (email authentication), DMARC policies, and domain ownership verification (Google, Microsoft).
Why use DNS lookup?
DNS lookup helps diagnose website issues, verify DNS propagation after changes, check email configuration, and audit domain security settings.
