WHOIS / RDAP Lookup

Look up public registration data for a domain, public IP address, or ASN using RDAP. The result can show registry records, network ranges, status fields, and dates when the public registry returns them.

WHOIS / RDAP Lookup: answer first

      
Look up public RDAP registry records for domains, IP addresses, and ASNs. Use the result as an observable public-signal check with stated limitations, not as an absolute guarantee.

WHOIS / RDAP Lookup: what this tool does

  
  

  

    
Looks up public domain, IP, and ASN registry records through RDAP.

  

  

    

      
How to use

      
  1. Enter one domain, public IP address or ASN - example.com, 8.8.8.8 or AS15169.
  2. Read the registry, status and date fields before any free-text remarks.
  3. Follow the referral to the responsible registry when the bootstrap answer is thin.

    

    

      
What the result means

      
The answer comes from official RDAP endpoints reached through the IANA bootstrap files, so it is what the responsible registry publishes: registrar, status codes, creation and expiry dates, and network or ASN allocation records.

    

    

      
Limitations

      
  • RDAP coverage varies by registry. Some return sparse records, some rate-limit, some redact fields entirely.
  • Registrant contact details are commonly withheld under privacy rules and are not shown here.
  • Registry data describes allocation and registration. It does not establish who operates a service on that name or address today.

    

  

  

    
WHOIS Lookup — Common Questions

    

      What information does a WHOIS lookup show?
      
A WHOIS lookup returns publicly available domain registration data: registrar name, registration and expiry dates, nameservers, and (when not privacy-protected) the registrant name, organisation, and contact details. For IP addresses and ASNs, WHOIS returns the network owner, assigned block, and registry information from ARIN, RIPE, APNIC, or other regional registries.

    

    

      Why does WHOIS show privacy-protected or redacted contact details?
      
Since GDPR came into force (2018), most registrars redact personal contact information from public WHOIS records for domains registered to individuals in the EEA. Domain privacy services (offered by Namecheap, GoDaddy, Cloudflare, etc.) also replace registrant contact info with proxy details. The domain is still registered to a real person — the registry just does not show it publicly. Legitimate legal requests to the registrar can still retrieve the real registrant.

    

    

      What is RDAP and how does it differ from WHOIS?
      
RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It returns structured JSON data instead of plain text, supports HTTPS, handles internationalised domain names (IDN) correctly, and allows partial searches. ICANN began requiring registrars to support RDAP in 2019. This tool uses RDAP, which means results are more structured and reliable than classic WHOIS, especially for newer TLDs.

    

    

      How do I find who owns a domain that has privacy protection?
      
For abuse, legal, or security matters, contact the registrar directly — they are required to respond to legitimate requests. You can find the registrar name from the WHOIS record (it is never redacted). File an abuse report through the registrar's abuse contact, which is also publicly listed. For ongoing investigations, law enforcement can serve a legal process to compel the registrar to disclose registrant identity.
