Read-only WHOIS/RDAP lookup for a domain or IP address. For domains it returns registrar, EPP domain-status codes, nameservers, registration/expiry/last-changed dates, and the abuse contact; for IPs it returns the network allocation (CIDR, name, type). Data is sourced live from the IANA RDAP bootstrap with an rdap.org fallback. Registrant personal data is usually GDPR-redacted — that is normal, not an error. Use to check domain ownership, age, or expiry, vet a suspicious domain, or find an abuse contact; for DNS records use lookup_dns instead. query is a domain name or an IPv4/IPv6 address. No auth, no side effects.
