+ * or for some error notification from network.
+ * This option is only available on linux and mac.
+ * @property {number} min_reply - Exit after sending number of ECHO_REQUEST
+ * @property {boolean} v6 - Use IPv4 (default) or IPv6
+ * @property {string} sourceAddr - source address for sending the ping
+ * @property {number} packetSize - Specifies the number of data bytes to be sent
+ *                                 Default: Linux / MAC: 56 Bytes,
