This lookup leaves your browser.The IP you type is sent to Duck Tools, then to the regional registry via RDAP and port-43 WHOIS. We also ask Cloudflare DNS for the reverse name. Fresh lookups share the daily WHOIS quota. We do not accept lookups from other websites.
No tracking.No analytics and no tracking cookies. Sign-in uses a session cookie and loads Cloudflare Turnstile only when you open the account dialog.
Short-lived, not a dossier.Queries are rate-limited. WHOIS answers are cached so repeats are fast and do not use quota. We do not sell them or keep a history under your name.

IP Network

WHOIS and reverse DNS for any IPv4 or IPv6 address.

Type an IP and see the allocated network, the organisation, reverse DNS and the raw RIR record. Lookups go through Duck Tools to public RDAP and port-43 WHOIS — other sites cannot embed this endpoint.

How it works

Type an IPv4 or IPv6 address, or open a link from DNS Lookup.
We ask the regional registry (RDAP) and port-43 WHOIS for the allocated block.
Reverse DNS comes from Cloudflare. Fresh WHOIS is cached and shares the daily quota.
Other sites cannot embed or reuse this lookup.
