Looks up domain registration, IP network allocation or AS number data through RDAP — the registries' structured successor to WHOIS — via the rdap.org bootstrap: registration, update and expiry dates (with days left), EPP status codes explained, nameservers and DNSSEC, the registrar with its IANA ID and abuse contact, and registrant/admin/technical contacts parsed from vCard, stating plainly when a registry redacts them (GDPR). IP lookups show the range, CIDR, type, country and holder; AS lookups the name, country and holder. Registries that lack RDAP or CORS are reported with a curl command to try instead. Nothing is stored.
