How it works
DNS records tell the internet where to find your website, mail servers, and other services. This tool looks up A, MX, TXT, NS, and CNAME records for a domain in one pass, so you can verify your setup or troubleshoot a misconfiguration.
A single wrong or missing record — an MX pointing nowhere, a stale A record left over from a migration — can quietly break email delivery or send visitors to the wrong server for hours before anyone notices.
Frequently asked questions
Why does a DNS change I just made not show up yet?
DNS records have a TTL (time-to-live) that controls how long resolvers cache them — depending on the record's TTL setting, propagation can take anywhere from a few minutes to 24-48 hours.
What's the difference between an A record and a CNAME?
An A record points a domain directly to an IP address; a CNAME points it to another domain name instead, which then resolves to an IP. CNAMEs are useful when the target IP might change, since only one place needs updating.
Why does my domain have multiple MX records?
Multiple MX records provide mail delivery redundancy, each with a priority number — mail servers try the lowest-priority (highest-preference) record first, and fall back to others if it's unreachable.
