What Is a WHOIS Lookup?
A WHOIS lookup shows the public registration record of a domain name. It tells you which registrar the domain was bought through, when it was registered, when it was last changed and when it expires, its status codes and the name servers it uses.
The record is held by the registry of the domain extension, such as Verisign for .com, and by the registrar. Most registries now answer through RDAP, the modern replacement for the old WHOIS text service. This tool asks RDAP first and falls back to classic WHOIS on port 43 for extensions that have no RDAP service.
Because of privacy rules such as GDPR, the owner's name, address and phone number are normally hidden. A lookup therefore tells you about the domain, not about the person behind it.
Everything the Registry Will Tell You.
The answer comes straight from the registry of the domain extension, so it is the same record that registrars and hosting companies work from.
Registrar and status
Which company manages the domain, and whether it is locked against transfers or has other restrictions.
Key dates
When the domain was registered, last changed and when it expires, with the days left, so you can renew in time.
Name servers and DNSSEC
Where the domain points for DNS, and whether DNSSEC signing is switched on.
Privacy built in
Most registries hide the owner's personal details. You see the registrar and the abuse contact, not a home address.
Common Problems and Fixes.
Most WHOIS questions come down to one of these six.
The domain shows as not registered
The registry has no record, so the name may be free to register. Check the spelling and the extension. If you expected it to exist, it may have expired and been deleted.
The status says clientHold or pendingDelete
The domain will not work. clientHold usually means an unpaid renewal or a dispute at the registrar. pendingDelete means the domain is about to be released. Contact the registrar quickly.
The name servers are not the ones I set
Check the name servers in your registrar's control panel, then allow up to 48 hours for the change to spread. Use the DNS lookup to see what the name servers answer right now.
The owner details are hidden
This is normal. To contact an owner, use the contact form of the registrar or the website itself. For abuse reports, use the registrar abuse contact shown in the result.
The domain is close to expiry
Renew it at the registrar now. After expiry there is a short grace period, but renewal can cost more, and the website and email stop working as soon as the name goes on hold.
I want to move the domain to another registrar
Look for the registrar lock status (client transfer prohibited). Ask your current registrar to unlock it and send you the transfer (EPP) code, then start the transfer at the new registrar.
