Domain Age Checker

The tool queries the registry's RDAP service, which it finds through the IANA bootstrap registry, and reads the registration event from the record. It then calculates the difference between that date and the current date in UTC and shows it as years, months and days, along with the total number of days.

Because the source is the registry itself, the result is not affected by website archives, first-seen dates in search engines or the age of the content hosted on the domain.

A successful lookup produces an INFO finding with the age and the registration date. Age is shown as information rather than PASS or FAIL because it is neither good nor bad on its own.

If the registry returns a record but does not include a registration event, the finding is UNKNOWN. Some country-code registries omit creation dates or publish them in a different field. If the extension has no RDAP service at all, as with .np, you will see a note that RDAP is unsupported for that extension.

The registration date reflects the current registration. A domain that has been transferred between registrars or owners usually keeps its original date, because transfers do not create a new registration. A domain that expired, was deleted and then registered again by someone else normally gets a fresh date, even though the name may have a long history.

Age is a useful signal when you are assessing a vendor, a link in a suspicious message or a name you are considering buying. Very new domains are common in phishing campaigns, but plenty of legitimate projects are new too, so treat age as one input rather than a verdict. For the full record, including registrar and status codes, use the RDAP / WHOIS Lookup.

The registration date is one of several events a registry records. The expiration date tells you how long the current term runs, and a domain registered years ago can still lapse next week; the Domain Expiry tool reports it with the number of days remaining. A last changed date, shown in the full RDAP record, reflects the most recent update to the registration, such as a nameserver change or renewal.

Taken together, these dates tell a fuller story than age alone. An old domain that changed nameservers yesterday and expires soon deserves a closer look than its age suggests, while a recent registration with a multi-year term suggests a planned, longer-term project. Domain expiry explained describes the stages a registration passes through.
