Enter a domain to see the nameservers it uses - the servers that hold all of its DNS records.

What is a nameserver?

A nameserver is the DNS server that holds a domain's DNS records and answers queries for them, for example ns1.example-host.com. A domain's nameservers are set at its registrar, and only the nameservers listed there are authoritative - DNS records edited at any other provider have no effect.

How to find a domain's nameservers

Enter the domain name in the box above.
Click Look Up Nameservers.
Compare the nameservers shown with the ones your DNS or hosting provider asks you to use.
If you have just changed them at your registrar, allow up to 24-48 hours for the change to spread across the internet.

Nameservers determine WHERE a domain's DNS records actually live and get managed - if you've recently moved a domain to a new DNS provider (or a new host that manages DNS for you), the nameservers shown here confirm whether that migration has actually taken effect, since any DNS record change you make will have no effect at all until the domain's nameservers correctly point to the provider where you're making that change. JustChecker tracks your DNS records continuously and alerts you the moment something changes.

Frequently Asked Questions

Pointing the domain at your new host's nameservers lets the host manage all DNS records for you. Remember to recreate any email (MX) and verification records there.

Usually a few hours, but it can take up to 48 hours, because the registry and resolvers cache the old nameservers. The DNS Propagation Checker shows progress.

The change may not have been saved at the registrar (nameservers are set there, not at the DNS host), or it is still propagating.
