Frequently Asked Questions
What is DNS and why should I look up DNS records?
DNS (Domain Name System) translates domain names into IP addresses and stores various record types that control email delivery, domain verification, and more. Looking up DNS records helps you verify configuration, troubleshoot connectivity issues, and audit email security settings like SPF, DKIM, and DMARC.
What DNS record types does this tool support?
This tool supports querying A (IPv4 address), AAAA (IPv6 address), CNAME (canonical name), MX (mail exchange), NS (name server), TXT (text records), SOA (start of authority), SRV (service), CAA (certification authority authorization), and PTR (pointer/reverse DNS) records.
How does this tool work? Is my data safe?
All DNS queries go through Cloudflare's DNS-over-HTTPS (DoH) API, which encrypts your queries with HTTPS. No data is stored on any server — this is a static tool that runs entirely in your browser. Your lookup history is never sent anywhere.
