NAMESERVER LOOKUP

Find out who
hosts the DNS.

Look up a domain’s nameservers and see which DNS provider runs them,
plus all its common DNS records.

A domain or full URL. Nameservers are read from the registered domain. Live DNS lookup

Your browser sends the domain you search directly to Google Public DNS, RIPEstat, and the domain’s registry to fetch public records. We don’t store your searches on our servers.

CURIOUS? TRY

One domain. The bigger picture.

Hosting, registrar, expiry, DNS records, email, and security details appear here.

PUBLIC DATA. ONE SIMPLE LOOKUP.
THE SHORT VERSION

Nameservers and DNS hosting

A domain’s nameservers (its NS records) are the servers that answer DNS questions for it. Whoever runs them, whether that’s your registrar, Cloudflare, Amazon Route 53, or your web host, is your DNS host, and that’s where you edit the domain’s records.

DNS hosting, web hosting, and email hosting are often three different companies. WhoHostIt shows all three, so you can see where each change needs to be made.

Common questions

How do I find out who hosts DNS for my domain?

Enter the domain above. We read its NS records and name the DNS provider when we recognise it, for example *.ns.cloudflare.com for Cloudflare or awsdns for Amazon Route 53.

How do I change my nameservers?

Nameservers are set at your domain registrar, not at your DNS host. The Registration section shows which registrar that is.

Why do nameserver changes take time?

DNS resolvers cache NS records for their time to live (TTL), and the parent registry sets its own TTL too, so a change can take up to a day or two to be seen everywhere.

SMALL TOOL. CLEAR ANSWERS.

Under the hood, in three steps.

01

You bring the domain

Paste a domain or a full URL. We’ll find the hostname and its registered parent domain.

02

We connect the dots

Public DNS, routing data, and registry records reveal the domain’s infrastructure.
