Enter a domain to see its nameservers and who hosts its DNS. Free, instant, no signup.
A free nameserver lookup. Enter a domain and it queries DNS for the domain's NS records and its SOA primary nameserver, and names the DNS provider when it recognises one, such as Cloudflare, Route 53 or GoDaddy. No signup, no email.
The nameservers listed for a domain are the servers that hold its DNS records: where the website lives, where mail goes, and which services are verified. Moving to a new DNS provider means changing these at the registrar.
For all record types at once, including A, MX and TXT, use the DNS Lookup tool.
Enter the domain above, for example example.com. The tool queries its NS records and lists them, and names the DNS provider when it can.
Nameservers answer DNS questions for your domain, such as which IP address serves your website. Your web host runs the site itself. They are often different companies, for example DNS at Cloudflare and hosting elsewhere.
DNS answers are cached, and changes at the registry can take hours to reach every resolver. Check again later, and remember that nameserver changes are made at your domain registrar.
