Worked examples for IP WHOIS: the current registration record of a well-known public IP address, and the answer to an IPv6 address. ipwhois.asn and its asn_* fields describe the autonomous system that announces the address; ipwhois.asn_registry names the regional internet registry (RIR) the record comes from.

Every example is a real response from September 24, 2026. ipwhois.network is the registered network that contains the address; ipwhois.entities lists the handles of the organizations and contacts attached to it and ipwhois.objects gives the details of each, keyed by handle. Contacts of natural persons (names, addresses, phone numbers, e-mail addresses) are redacted, and e-mail addresses other than role mailboxes are shown as user@<domain>.
