SwiftIP2ASN 0.5.1 introduces the ip2asn executable for zero-configuration bundled IPv4 and IPv6 lookups. The lookup verb can be explicit or implied: ip2asn 1.1.1.1.
New inspect and validate verbs emit deterministic JSON for local and CI diagnostics. Validation fully parses ULT2 artifacts and can verify the manifest output digest, build identifier, format, counts, and generation timestamp. The bundled and current hosted R2 artifacts pass this validation.
The previous ip2asn-tools executable and format-specific verbs remain compatibility aliases during the 0.x release line. See CHANGELOG.md for complete details.
