Pure-Dart multi-server DNS lookup + Whois client. CLI emits JSON suitable for shell pipelines.

example/example.dart

// Minimal example for pub.dev: query DNS across multiple resolvers and run a
// Whois lookup for one hostname. Run from the package root:
//
//   dart run example/example.dart google.com
//
// See `example/basic_usage.dart` for an identical, more talkative variant.
