Nameserver Lookup
Look up the nameservers any domain uses and instantly see which DNS provider sits behind them.
What nameservers tell you
A domain's nameservers point to the DNS provider that answers queries for it — for example Cloudflare, AWS Route 53, Google Cloud DNS, or your registrar's own DNS. The nameserver hostnames reveal which provider controls a domain's DNS, which is the first thing to check when diagnosing where a site or its email is actually hosted.
Why watch for nameserver changes
A change in nameservers means a domain's DNS has moved to a different provider. That can be a planned migration — or an early warning sign of a hijack. We identify the provider behind each nameserver so you can confirm the change is expected.
Frequently asked questions
Are these the registry or the live DNS nameservers?
We show the nameservers recorded at the registry, which is what controls delegation for the domain.
Can I be alerted when nameservers change?
Yes. A free account watches your domains and emails you when their nameservers change.
