DNS records map your domain to servers, A/AAAA (IP), MX (mail), TXT (verification/SPF), NS (nameservers). This tool queries live DNS for any domain and lists every record type.
What is DNS Lookup Tool?
A DNS lookup reveals the DNS records behind a domain, the settings that route your website, email, and verification services. It's an essential check when a site won't load, email bounces, or you're migrating hosts.
How it works
DNS (Domain Name System) translates a domain like example.com into the IP address of its server. A lookup queries records such as A (address), MX (mail), CNAME (aliases), TXT (verification), and NS (nameservers) to show how a domain is configured.
How to use this tool
Enter a domain name. The tool returns its DNS records so you can confirm they point where they should, useful after changing hosts, setting up email, or debugging downtime.
Why it matters
Most 'the site is down' or 'email stopped working' emergencies trace back to a DNS record that's missing, wrong, or hasn't propagated. A quick lookup tells you whether the problem is DNS or something else, saving hours of guesswork.
Frequently asked questions
What is a DNS record?
An instruction stored in the DNS that tells the internet how to handle a domain, where its website lives (A record), where its email goes (MX record), and more.
Why isn't my DNS change working yet?
DNS changes take time to propagate, anywhere from minutes to 48 hours depending on the record's TTL. A lookup shows the currently-live value so you know if it's updated.
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 one domain name to another. Use A records for root domains and CNAMEs for subdomains like www.
