A WHOIS Lookup and a domain's true age

Enter a domain name to see its registration time, its expiry time, the registrar that holds it and its nameservers. What comes back is exactly what the registry publishes, without a middleman and without any gloss.

  • No sign-up
  • Works with .ir
  • Standard RDAP protocol

Shows at no cost how old a domain is, when it expires, which registrar holds it, and which nameservers it points to.

  • What it costs Free
  • Data source Our own server
  • Access No sign-up

This tool executes on our own infrastructure with no purchased data behind it, so it costs nothing and stays that way. Its only limit is a daily cap that stops one bot from taking the whole capacity. The daily cap is measured per visitor. If you need more, a free account lifts your limit.

The short answer

A WHOIS lookup means reading a domain's registration file directly at the registry: the registration time, the expiry time, the registrar, the domain status and the nameservers. For international extensions these items usually come back in full; for the .ir extension only some of them do, because the Iranian registry does not release the dates publicly.

The most valuable figure this lookup yields is domain age, and in a decision it carries more weight than people assume. A ten-year-old domain that has been renewed throughout holds a history in Google that a freshly registered one does not. That does not mean age on its own earns rankings, because it does not; it means that with two domains on the table, the one with the older file is the better place to start.

The second use is the one site owners tend to recall too late: the expiry date. A domain left unrenewed first stops resolving and then falls open, and once somebody else claims it, getting it back is effectively impossible. If you cannot recite the expiry date of your main business domain, run this check once right now.

The third item worth reading is the nameservers. They tell you who controls the domain's DNS, which is not necessarily where the site is hosted. When a site is down and nobody recalls where the settings sit, this list is the first place to check.

The output you receive

The exact meaning of each output column. Read this before your first run so you do not misread a value.

Domain age
The span from the registration date to today, shown only when the registry publishes that date openly; for .ir it is usually not available.

The data source and method

Most extensions are read through the standard RDAP protocol; .ir domains are queried directly against whois.nic.ir, and that server does not publish registration or expiry dates openly, a constraint of the registry itself rather than of this tool.

The situations where it helps

Before you buy a pre-owned domain, or to gauge how far your own domain sits from its expiry date.

Where it falls short

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.

A lesson from working with 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.

Common questions about this tool

Why is there no registration date for an .ir domain?

Because the Iranian domain registry does not release it in the public WHOIS response. Any tool that shows an exact registration date for an .ir domain has either guessed it from elsewhere or fabricated it. We leave the field blank, because a missing value and a zero are not the same thing.

How long does a WHOIS lookup take, and are there limits?

Usually within a few seconds. There is a daily per-visitor cap to curb abuse; if you need more, open a free account and the limit rises.

Can I find out who owns a site?

In most cases, no. Since 2018 the owner's personal details have been hidden on most domains. What is left is the registrar name and the nameservers, useful for identifying the hosting company but not the individual.
