WHOIS Lookup and the domain real age
Type a domain and see when it was registered, when it expires, which registrar holds it and which nameservers it points to. The answer is whatever the registry itself publishes, with no middleman and no interpretation.

The short answer
A WHOIS lookup reads a domain registration file straight from the registry: registration date, expiry date, registrar, domain status and nameservers. For international domains all of that usually comes back; for .ir domains only part of it does, because the Iranian registry does not publish the dates publicly.
The most useful figure this lookup produces is domain age, and it carries more weight in a decision than people expect. A ten year old domain that has been renewed all along has a history in Google that a freshly registered one does not. That does not mean age alone earns rankings, because it does not; it means that when two domains are on the table, the one with the older file is the better starting point.
The second use is the one site owners usually remember too late: the expiry date. A domain that is not renewed first stops resolving and then becomes available, and recovering it once somebody else takes it is effectively impossible. If you cannot recite the expiry date of your main business domain, check it once right now.
The third item worth reading is the nameservers. They tell you who holds the domain DNS, which is not necessarily where the site is hosted. When a site is down and nobody remembers where the settings live, this list is the first place to look.
What you get back
What each output column actually means. Read this before your first run so you do not misread a number.
- Domain age
- From the registration date to today, only when the registry publishes this date publicly (usually unavailable for .ir).
Where the data comes from
For most extensions, the standard RDAP protocol is used; for .ir domains, it queries whois.nic.ir directly (which does not publish registration/expiry dates publicly, a limitation of the registry itself, not this tool).
When it helps
Before buying a second-hand domain, or to check how close your own domain is to its expiry date.
Where it does not help
For .ir domains the registration and expiry dates usually come back empty, and the domain-age column stays empty with them. That is the Iranian registry own limitation, not this tool: it does not publish those two dates in the public WHOIS response. If you own an .ir domain and want its expiry date, your registrar panel is the only correct place. Second point: since GDPR took effect in 2018, the owner name and email are hidden on most international domains too, sitting behind the registrar privacy service, so if you are looking for who owns this site, WHOIS almost never answers that.
One thing we learned using it
When you are checking a domain to buy, do not read only the age, read the status too. A domain in redemptionPeriod or pendingDelete is not really free yet and the previous owner may reclaim it tomorrow, yet most domain marketplaces advertise exactly that state as coming soon.
What it costs
This tool runs on our own server and we buy no data for it, so it is free and stays free. It only carries a daily cap so a bot cannot swallow the whole capacity.
The daily cap is counted per visitor. If you need more, a free account raises your limit.
Questions about this tool
Why is there no registration date for an .ir domain?
Because the Iranian domain registry does not publish it in the public WHOIS response. Any tool that shows an exact registration date for an .ir domain either guessed it from another source or made it up. We leave the field empty, because a missing value and a zero are different things.
How long does a WHOIS lookup take, and are there limits?
Usually a few seconds. To prevent abuse there is a daily cap per visitor; if you need more, create a free account and your limit goes up.
Can I find out who owns a site?
In most cases, no. Since 2018 the owner personal details are hidden on most domains. What remains is the registrar name and the nameservers, useful for identifying the hosting company but not the person.
