Which record types can I look up?

A, AAAA, MX, TXT, NS and CNAME records — the most commonly needed DNS record types for troubleshooting and verification.

Why would I need to check MX records specifically?

MX records control where email for a domain is delivered, so checking them is a common step when troubleshooting email delivery issues or verifying an email provider migration.

Does the lookup reflect the current live DNS, or cached data?

It queries current DNS records — keep in mind DNS changes can take time to propagate globally, so results may briefly differ from what you expect right after making a change.

Does DNS Lookup upload my files to a server?

No. DNS Lookup runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Checking a domain's DNS records — A, AAAA, MX, TXT, NS, CNAME — is routine work when troubleshooting email delivery, verifying a domain migration, or debugging why a site isn't resolving correctly, and command-line DNS tools aren't something everyone has set up. This tool looks up a domain's A, AAAA, MX, TXT, NS and CNAME records directly in the browser, giving you the same information without needing command-line tools.
