What does the domain age checker show?

Check any domain free

Visit /domain-age-checker without logging in. Enter a bare domain, a subdomain or a complete web address—whichever you use, the registered domain itself is what gets looked up. The checker returns the registration record from the public registry: how old the domain is (in years, months and days), when the registry recorded it, its registration date, expiry date, last update date, which registrar holds it, DNSSEC signing status and the nameservers. The page shows you when the record was checked.

Domain info on each listing

Every listing has a Domain info box in its metrics section. This shows the company's own domain registration record—age, registration and expiry dates, registrar and DNSSEC status—with a link to the full details on the checker. We refresh this record roughly every week.

Data source and gaps

All information comes from RDAP, the public registry standard that replaced WHOIS. Some registries, including several country-code registries, do not publish RDAP data; when this happens, nothing can be shown and the page tells you so. If a registry does not reply, wait a few minutes before you try again.

What age really means

Domain age counts from the current registration only. If a domain lapses and someone registers it again, the age resets to that new registration date. On Alternative Biz, domain age does not change how listings rank.
