/** Asynchronous and cancellable DNS resolver

 * Resolver provides cancellable synchronous and asynchronous DNS resolution,
 * for hostnames (lookup_by_address(), lookup_by_name() and their async
 * variants) and SRV (service) records (lookup_service()).
 *
 * NetworkAddress and NetworkService provide wrappers around Resolver
 * functionality that also implement SocketConnectable, making it easy to
 * connect to a remote host/service.
