public static String getLocalIpv4Address(){
    try {
        String ipv4;
        List  nilist = Collections.list(NetworkInterface.getNetworkInterfaces());
        if(nilist.size() > 0){
            for (NetworkInterface ni: nilist){
                List  ialist = Collections.list(ni.getInetAddresses());
                if(ialist.size()>0){
                    for (InetAddress address: ialist){
                        if (!address.isLoopbackAddress() && InetAddressUtils.isIPv4Address(ipv4=address.getHostAddress())){ 
                            return ipv4;
                        }
                    }
                }

            }
        }

    } catch (SocketException ex) {

    }
    return "";
}

Should this be ok ? This function will return ipv4 (in xxx.xxx.xxx.xxx pattern) only if available.

Please note that those hexadecimal value you mentioned should be an ipv6 address.
