Website Checker
← All toolsEnter a URL to check its domain age, expiration date, owner, last-updated date, registrar, DNSSEC status, and a raw legacy Whois record, plus whether the site is currently reachable. Any URL can be checked, not just a tracked Dodolytics website. Free tool, nothing you check is stored; results are shown once and not saved.
Two honest limitations, not glossed over: registrant ("Owner") data is redacted by most registries by default since 2018 (GDPR/ICANN policy), so this frequently reads "not disclosed" even for a real, valid domain. That's the registry withholding it, not this tool failing. And the Whois tab shows the real registry's own raw text exactly as returned, unparsed. Whois has no consistent format across registries, unlike the structured data in the other tabs.
What is a website checker tool?
A website checker looks up the public registration and availability facts about a domain — who registered it and when, when it expires, who the registrar is, whether DNSSEC is enabled, and whether the site is actually reachable right now — pulled from the domain's real RDAP and Whois records and a live HTTP check, rather than anything the website itself claims about itself.
How do I use it?
Enter a domain or URL above. This tool checks the site's live availability, looks up its RDAP registration data (creation date, expiration date, registrar, DNSSEC status, registrant), and fetches its raw legacy Whois record too — shown across four tabs: Overview, Registrar, Owner, and Whois.
Why is it useful?
- Quickly check when a domain was registered and how much longer it has before it expires — useful before buying or evaluating a domain, or keeping an eye on one you already own.
- Confirms a site is actually up and responding right now, rather than just assuming it is.
- Surfaces registrar and DNSSEC status in one place, useful for due diligence or troubleshooting a domain issue.
- Free, no sign-up required, and nothing about a check is stored — check any domain, not just one you already track.
