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.
