WHOIS lookup
See who's behind any domain — who owns it, whether it's available, and its full registration details — all with Phluit's free WHOIS lookup tool.
Everything you can do
with a WHOIS search
Look up a Domain Check domain availability
Not sure if a name is taken? Type it into the search above and we'll tell you in a second whether it's already registered or free to grab.
Find domain owner information
Look up the registrar behind a domain, its nameservers and technical details — plus the registrant organization whenever it's public.
See when a domain expires
A taken domain isn't always a lost cause. Check its expiry date — some lapse and free up again, and you could be first in line to register it.
Whenever someone registers a domain, they have to submit info to ICANN—think of it as signing your name in the internet's public guestbook. This info can be accessed using our free WHOIS lookup tool to find out who owns the domain you're searching.
You can also see their contact info, when the domain was registered and when it expires. Plus, with data sourced from ICANN-compliant registry records, you know you're getting info straight from the source.
As the internet shifts to RDAP (Registration Data Access Protocol)—a newer, more structured way to access domain registration information with stronger GDPR privacy protections—Phluit's WHOIS tool supports both RDAP and WHOIS, so you're covered either way.

Domain taken?
Here's what
you can do
- 01
Check the WHOIS record. Run the search above to confirm the name is actually registered — some are only reserved or about to expire.
- 02
Find the domain owner. If the record isn't private, you can often reach the owner and make them an offer for the name.
- 03
Tweak the name. Add a word, switch up the spelling, or try a different ending like .net, .co or .store.
- 04
Pick a fresh name. Brainstorm new ideas and check them with our domain search to find one that's available.

What is the WHOIS database?
WHOIS is the public record system for domain names. Whenever a domain is registered, its registrar publishes the key details — the registrar of record, the registration and expiry dates, the nameservers and the domain's status — under rules set by ICANN, the body that coordinates domain names worldwide. A WHOIS lookup simply reads that record so anyone can see what's currently on file for a given domain.
What information does a WHOIS lookup show?
A typical record includes the registrar managing the domain, the registration, last-updated and expiry dates, the nameservers, the status codes (such as 'client transfer prohibited') and whether DNSSEC is enabled. Where it hasn't been hidden for privacy, you may also see the registrant organization. Personal contact details are usually redacted by default.
What's the difference between WHOIS and RDAP?
They serve the same purpose in two different formats. WHOIS is the original protocol from the 1980s and returns plain, free-form text. RDAP (Registration Data Access Protocol) is its modern, ICANN-backed successor: it returns clean, structured data over HTTPS with consistent fields and built-in handling for privacy rules like GDPR. ICANN has been phasing out legacy WHOIS in favor of RDAP, and Phluit's lookup uses RDAP so your results are accurate, standardized and up to date.
How can I find out who owns a domain name?
Enter the domain in the search box at the top of this page. If the owner hasn't enabled privacy protection, the registrant organization appears in the record. Keep in mind that most owners — and virtually all individuals — keep their details private, so you'll often see the registrar rather than a personal name. That's by design, and it protects owners from spam and misuse.
Can I contact the domain owner using WHOIS?
Sometimes, but usually only indirectly. Because of privacy laws like GDPR, personal emails and phone numbers are redacted from most records. What you can generally rely on is the registrar's abuse contact, which is used to report misuse of a domain. For ordinary outreach, many domains route messages through the registrar rather than exposing the owner's private details.
Is a WHOIS lookup free?
Yes. Phluit's WHOIS lookup is completely free, needs no account, and has no lookup limits for normal use — check as many domains as you like.
Is it legal to use a WHOIS lookup tool?
Yes. WHOIS and RDAP data is published specifically so people can identify and contact those responsible for a domain for legitimate reasons, and looking it up is legal worldwide. The one rule: the data may not be used for spam, bulk harvesting or other prohibited purposes.
How accurate is WHOIS data?
The structural fields — registrar, dates, nameservers, status and DNSSEC — come straight from the domain's authoritative registry, so they're highly accurate and refresh in near real time. Registrant contact fields depend on what the owner supplied and whether privacy protection is switched on, so those can be limited or masked.
How can I protect my privacy in the WHOIS database?
Register your domain with a provider that includes WHOIS privacy protection. At Phluit, domain privacy is included free for life on eligible domains — your name, address, email and phone stay off the public record automatically and are replaced with protected contact details. You can turn it on in a click when you register or transfer a domain to us.
What is the difference between a DNS lookup and a WHOIS lookup?
They answer different questions. A WHOIS lookup is about ownership and registration — who holds the domain, when it expires and its status. A DNS lookup is about connectivity — the A, MX and other records that decide where the domain points for websites and email. In short: WHOIS tells you who owns a domain; DNS tells you how it works.
