Query any DNS record type from authoritative resolvers. Enter a domain to look up A, MX, TXT, CNAME, NS, SOA and more.
A DNS (Domain Name System) lookup queries DNS records associated with a domain name. DNS translates human-readable domain names like example.com into IP addresses that computers use to route traffic across the internet.
Each domain can have multiple DNS record types — A records point to IPv4 addresses, MX records route email, TXT records store verification tokens and policy data, and NS records identify authoritative nameservers.

A DNS lookup queries the DNS system to retrieve records associated with a domain name. It can return IP addresses (A/AAAA records), mail server information (MX), text records (TXT), and more.
DNS results can differ due to caching (TTL), propagation delays after recent changes, or different responses from authoritative vs recursive resolvers. Use our DNS Propagation Checker to compare results across multiple global locations.
TTL (Time to Live) is the number of seconds DNS resolvers will cache a record before re-querying. A lower TTL means changes propagate faster but increases query volume. Common values range from 300 seconds (5 minutes) to 86400 seconds (24 hours).
You can look up DNS records for any publicly registered domain. Private networks, local domains (.local, .internal), and domains using split-horizon DNS may return different results or no results at all.
