Domain registration
Registrar, registration date and expiry information from RDAP and WHOIS sources. Free, no signup, 5 checks a day.
You can open any section directly with a domain in the URL query string, then share that result page with someone else.
How to read this result
These notes explain what the check is showing, where the data comes from and what the main blind spots are.
Live registry data
Registration facts come from the registry's RDAP endpoint in real time — not a cached WHOIS scrape. What you see is what the registry publishes right now.
"Not published" is not "not registered"
Some registries redact data under GDPR, and some rate-limit lookups. An empty registration block means the registry did not return data — it does not mean the domain is available.
The two expiry clocks
The certificate and the registration expire independently, and the registration is the one that ends the domain itself. It usually renews on a card someone replaced two years ago — watch it twice a year.
TLD coverage
A handful of TLDs are not in the supported list. A lookup against one returns 'TLD unsupported' — nothing is wrong with the domain, the registry is simply not connected.
