Domain WHOIS, IP Registration and ASN Lookup
About Domain WHOIS, IP Registration and ASN Lookup
Look up domains, public IP ranges, registries, holders, countries, events, routing prefixes, and origin ASNs through RDAP and RIPE NCC.
How to use this tool
Enter a domain, public IP address, or ASN to retrieve RDAP registration details and RIPE NCC routing data. Review the network range, registry, holder, country, events, routing prefix, and origin ASN summary; expand Raw JSON for the complete response.
What to know
Queries contact external registry services. Registry country is not physical geolocation, holder data may be redacted, and rate limits or browser network restrictions can limit results.
