Free tool · DNS
Look up public DNS records and understand how a domain resolves. Enter a domain to see the records that decide where its traffic and mail go.
A and AAAA records give the IPv4 and IPv6 addresses the name points to. If they are missing, the site cannot be reached by name.
MX records name the servers that receive mail for the domain. NS records show which servers answer for the domain at all.
TXT records carry verification codes and mail policies, CNAME records point one name to another. Compare what you see with what you expect to have configured.
DNS answers are cached for the time set in each record (its TTL). After a change, some resolvers keep the old answer until that time passes.
It shows the common public record types. Records that exist only for subdomains are found by looking up the subdomain itself.
The name does not exist or its name servers did not answer. Check the spelling first, then the domain registration and the name server settings.
UptimeWire runs these checks for you around the clock and alerts you when something changes. Start with the free plan, no card needed.
