How to Find Out Who Owns a Domain and Who Hosts It

The Short Answer

Every domain has a public record. You can read it for free at lookup.icann.org. It shows which registrar the domain is with, when it was created and when it expires. It may or may not show the owner, because most records now hide personal details for privacy.

To find out who hosts the website and who handles the email, you look at the domain's DNS records. Those point to the companies doing the work. Our free DNS lookup tool shows them in a few seconds.

Most business owners ask this question about their own domain. A web designer moved on, an employee left, or nobody remembers who set it up. This guide covers both cases.

Step 1. Check the Registration Record

1. Go to lookup.icann.org.
2. Type the domain, like yourshop.com, and search.
3. Read the results.

You will usually see these things.

• Registrar. The company the domain is registered through. This is the most useful line.
• Created and expiry dates. Write the expiry date down now.
• Status codes. Lines like "client transfer prohibited" are normal locks, not a problem.
• Nameservers. The servers that answer DNS for the domain. These often name the host.
• Registrant. The owner. This is often marked as redacted or shows a privacy service.

Why the owner is often hidden

Since privacy laws tightened in 2018, most registrars hide personal names, emails and phone numbers in public records. Many people also pay for or get free domain privacy, which swaps their details for a forwarding service. So a hidden owner is normal. It does not mean anything shady.

WHOIS and RDAP

You may have heard of WHOIS lookups. ICANN has moved to a newer system called RDAP, which does the same job in a cleaner format. Since January 28, 2025, registries and registrars for generic endings are no longer required to run the old WHOIS service. ICANN Lookup uses RDAP, so you do not have to think about it.

Step 2. Find Who Hosts the Website

The registrar and the host are often two different companies. To find the host, check where the domain points.

1. Open our DNS lookup tool and enter the domain.
2. Look at the NS records. Names like ns1.somehost.com often tell you who manages the DNS, and that is often the host.
3. Look at the A record or CNAME for the domain and for www. These point to the server that serves the website.
4. If the A record is just a number, search that IP address with an IP lookup site to see which network owns it.

Some sites sit behind a service like Cloudflare, which hides the real server for speed and security. In that case the lookup shows Cloudflare, and the host behind it is only visible to whoever controls the Cloudflare account.

Our plain guide to DNS records explains what each record type means.

Step 3. Find Who Runs the Email

Look at the MX records in the same DNS lookup.

• Names ending in google.com mean Google Workspace.
• Names ending in outlook.com or protection.outlook.com mean Microsoft 365.
• Names with your host's name in them mean email through your hosting plan.

This matters before any move. If you change hosts and the email records do not come along, your email stops. Our business email guide covers how email on your own domain works.

When the Domain Is Yours but Not in Your Name

This is the most common reason owners end up here. Someone else registered your business domain and now cannot be reached, or will not hand it over.

1. Find the registrar using Step 1.
2. Search your old email for messages from that registrar. Receipts and renewal notices often name the account.
3. Ask the person who set it up to move it into your name. A good designer or agency will do this without a fight.
4. Contact the registrar's support. Explain that the domain belongs to your business and ask what proof they need. Business records, invoices and a website history can all help.
5. Watch the expiry date. If it lapses before you get control, renew it if the registrar lets you, or you may lose it.

Once you have the login, change the account email to one the business controls, turn on two factor sign in, and set the domain to auto renew.

When the Domain Belongs to Someone Else

Maybe you want a name that is already taken. A few honest options exist.

• Check if it is for sale. Some domains show a for sale page or list a broker.
• Contact the owner through the registrar. Many registrars offer a contact form or forwarding address that protects the owner's privacy.
• Use ICANN's request service. ICANN runs a Registration Data Request Service at rdrs.icann.org for people with a lawful reason to ask for hidden details, like a trademark problem. A registrar decides each request.
• Pick a different name. Our domain name ideas tool and our guide on how to pick a domain name can help you find one that works.

What to Write Down Today

Do this for your own domain, even if nothing is wrong.

• Registrar and the login email.
• Expiry date, and whether auto renew is on.
• Who hosts the website.
• Who runs the email.
• Who else has a login.

Keep it with your other business records. If a designer leaves or a card expires, you will know exactly who to call. Our guide on what happens when a domain expires explains why the expiry date matters so much.

Common Questions

How do I find out who owns a domain?

Search the domain at lookup.icann.org. You will see the registrar and key dates. The owner's name is often hidden for privacy, so the registrar is usually your best lead.

Why is the domain owner listed as redacted?

Most registrars hide personal details in public records for privacy, and many owners use a privacy service. It is normal and does not mean anything is wrong.

How can I tell who hosts a website?

Run a DNS lookup on the domain. The nameservers and the A or CNAME records usually point to the hosting company. An IP lookup can name the network if the record is just a number.

Is WHOIS still used?

ICANN replaced WHOIS with RDAP. Since January 28, 2025, generic domain registries and registrars no longer have to run WHOIS. ICANN Lookup uses RDAP for you.

How do I find out who my domain is registered with?

Look it up at lookup.icann.org and read the Registrar line. Then search your email for receipts or renewal notices from that company.

What if my web designer owns my domain?

Ask them to move it into your business name. If they cannot be reached, contact the registrar's support with proof the business owns the name, and do it before the domain expires.

How do I find out who runs a domain's email?

Check the MX records with a DNS lookup. Google Workspace and Microsoft 365 records are easy to spot by name.
