WHOIS & RDAP lookup

Query the authoritative registry for a domain, IP address, or AS number. Uses RDAP (RFC 9082) with automatic discovery through the IANA bootstrap registries, falling back to port-43 WHOIS for TLDs that never deployed RDAP.

Optional lookups Each option costs an extra round trip to a third party, so they are off by default.
