Ping en java

[ipraetoriux]

...te dejo un ejemplo, la idea es usar InetAddress.isReachable();

Código Java:

public static boolean ping(String ipAddress) {
        try {
            final String IPADDRESS_PATTERN = "^([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\.([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\.([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\.([01]?\\d\\d?|2[0-4]\\d|25[0-5])$";
            Pattern pattern = Pattern.compile(IPADDRESS_PATTERN);
            Matcher matcher = pattern.matcher(ipAddress);
            if(matcher.matches()) {
                return InetAddress.getByName(ipAddress).isReachable(5000);
            } else {
                return false;
            }
        } catch (Exception ex) {
            Logger.getLogger(Utilities.class.getName()).log(Level.SEVERE, null, ex);
            return false;
        }
    }
