About the WHOIS / RDAP
This WHOIS tool looks up registration data for any domain name or IP address using RDAP, the modern, structured replacement for legacy WHOIS. For a domain you get the registrar, the registration, last-updated and expiry dates, the domain status codes (such as clientTransferProhibited) and the authoritative nameservers. For an IP address you get the owning network's range and country.
The query runs server-side against the public RDAP system, which returns clean JSON rather than the free-text WHOIS of old, so results are consistent and easy to read. Use it to check when a domain expires, see who the registrar is, confirm nameserver delegation, or find which network an IP belongs to.
How to use it
- Enter a domain name (example.com) or an IP address.
- Submit to query the RDAP system for its registration record.
- Review the registrar, key dates, status codes and nameservers.
- For an IP, note the network range and country of the owning block.
Examples
- Look up example.com to see its registrar and expiry date.
- Check a domain's status codes to confirm a registrar lock is in place.
- Query an IP like 8.8.8.8 to find the network and country it belongs to.
Frequently asked questions
What is the difference between WHOIS and RDAP?
RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. It returns structured JSON with consistent fields and supports access controls, where classic WHOIS returned unstructured text that varied by registry. This tool uses RDAP and presents the key fields.
Why are some contact details missing?
Since GDPR, most registries redact personal registrant contact data in public RDAP/WHOIS responses. You will reliably see the registrar, dates, status and nameservers, but not the registrant's name or email for most domains.
Can I look up any TLD?
Most modern gTLDs and many ccTLDs publish RDAP. A few registries do not, in which case no RDAP record is returned. The tool will tell you when that happens.
Does this show when a domain expires?
Yes. When the registry publishes it, the expiry (expiration) date is shown alongside the registration and last-updated dates.
