android 根據域名得到IP

    public static String GetInetAddress(String host) {
        String IPAddress = "";
        InetAddress ReturnStr1 = null;
        try {
            ReturnStr1 = java.net.InetAddress.getByName(host);
            IPAddress = ReturnStr1.getHostAddress();
        } catch (UnknownHostException e) {
            e.printStackTrace();
            return IPAddress;
        }
        return IPAddress;
    }

　　測試可用！
