About this free DNS lookup tool
DNS records are the internet's address book: A records point a domain at an IPv4 address, MX records route its email, TXT records hold verification tokens and security policies like SPF and DMARC, and NS records name the authoritative nameservers. Whether you are debugging email delivery, moving hosts or just curious, seeing the raw records is the fastest route to an answer.
This tool queries a live public resolver over encrypted DNS-over-HTTPS, so results reflect the records as they exist right now — no cached guesses. It is free, unlimited and needs no sign-up.
FAQs
What is a DNS lookup?
It shows the DNS records published for a domain — the instructions that tell the internet where a website is hosted, where its email goes and more. Common types are A (IPv4 address), MX (mail servers) and TXT (verification and security data).
Where does the data come from?
From a live public DNS resolver over encrypted HTTPS (DNS-over-HTTPS), so the results you see are the records as they exist on the internet right now.
Why do results differ from what I see in another tool?
DNS changes take time to propagate worldwide, and big sites use different records per region or per CDN edge. Two resolvers can legitimately return different answers for the same domain at the same moment.
What is TTL?
TTL (time to live) is the number of seconds a record may be cached before resolvers must ask again. A low TTL means changes take effect faster; a high TTL means fewer lookups.
