Question

I am trying to get hostname/computer name using this method. Unfortunately i only can get localhost but not other computer.

private String getHostName(String _strIP) {
    try {
        InetAddress inetAddress = InetAddress.getByName(_strIP);
        System.out.println("getHostAddress : " + inetAddress.getHostAddress());
        System.out.println("getHostName : " + inetAddress.getHostName());
        System.out.println("getCanonicalHostName : " + inetAddress.getCanonicalHostName());
        return inetAddress.getHostName();            
    } catch (UnknownHostException e) {
        e.printStackTrace();
    }
    return strDefaultHostName;
}

the result (not localhost)

getHostAddress : 192.168.2.139
getHostName : 192.168.2.139
getCanonicalHostName : 192.168.2.139

the result (localhost)

getHostAddress : 127.0.0.1
getHostName : localhost
getCanonicalHostName : localhost

Thank you

Your DNS is broken. Then IP-numbers are returned instead.
