java - 如何借助IP地址获取硬件设备序列号？

Question

有没有办法通过IP地址获取同一网络内硬件设备的序列号？

Answer 1

你可以尝试这样的事情

InetAddress address = InetAddress.getByName("192.168.1.55");
NetworkInterface ni = NetworkInterface.getByInetAddress(address);
  if (ni != null) {
     byte[] mac = ni.getHardwareAddress();
     StringBuilder sb = new StringBuilder();
     for (int i = 0; i < mac.length; i++) {
     sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
     }
    System.out.println(sb.toString());
  }
