Domain Info looks up a domain's registration date, expiry date, age, and registrar using WHOIS and RDAP. This is the one tool on this site that isn't fully client-side: WHOIS/RDAP protocols aren't reachable from browser JavaScript, so the domain name you type is sent to our server, which runs the lookup and sends back the result. That's the only data involved - no account required, and we don't store the domains people search.
How to use it
- Type a domain name into the box - with or without "https://" or "www.", it gets cleaned up automatically.
- Click "Check Domain" (or press enter).
- Wait a moment while the lookup runs on our server.
- Read the results: creation date, expiry date, computed age, and registrar.
Frequently asked questions
Why isn't this tool client-side like the others on this site?
Browsers can't speak WHOIS or RDAP directly - there's no fetch() for those protocols. So the domain name you submit is sent to our server, which runs the actual lookup and sends back the result.
Is the domain I search stored anywhere?
No - we run the lookup and return the result to your browser. We don't log or store the domains people search.
Can I paste a full URL instead of a bare domain?
Yes - paste something like https://www.example.com/page and it's automatically cleaned down to example.com before the lookup runs.
What does the Domain Age field mean?
The time between the domain's registration date and today, broken into years, months, and days, computed in your browser once the registration date comes back.
What happens if a domain can't be found?
You'll see an error message instead of a results table. Coverage depends on the domain's registry - some registries redact WHOIS data or aren't supported.
What's the difference between WHOIS and RDAP?
WHOIS is the older, plain-text lookup protocol domain registries have used for decades. RDAP is the newer, structured replacement ICANN has been pushing registries to adopt. This tool queries whichever one the domain's registry supports.
