BroadCast message over ip python windows 10

Question

I am trying to write a simple messenger that sends a broadcast msg to all the computer in the local network . The code works on windows 7 , Ubuntu 14.10 but when I am trying to use it on windows 10 , it even does not send an udp package to broadcast , its doing nothing (checked with wireshark, no outgoing packages)

import socket
import sys
import traceback

dest=('<broadcast>',10100)
UDPSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

UDPSock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
while True:
    data = raw_input("Enter message to send or type 'exit': ")
    UDPSock.sendto(data, dest)
    if data == "exit":
        break
UDPSock.close()

I recognized the same problem after updating to Win10. My WOL.py (Wakeup On Lan) does not work any more. Checked with tcpdump.

I found now a workaround.

# Broadcast it to the LAN.
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
sock.sendto(send_data, ('172.16.1.255', 9)

Changing the address from '<broadcast>' to the network address with broadcast bit's set works on my system.

E.g. I have a Class C Network with IP 172.16.1.x netmask 255.255.255.0. Changing '<broadcast>'to '172.16.1.255' does the trick. Normally this is done by the OS.
