Listen to multicast address range
I am writing an UDP client where I have to listen to the multicast address range 126.96.36.199 - 188.8.131.52.
Using the method "joinMulticastGroup" for each individual address takes very long:
For example: On Mac OS X it took several seconds, on Windows 7 it took more than a minute!
I tried it with Qt 4.8.6 and Qt 5.3.2 - no difference.
Is there a more efficient way to join a multicast address range?
Thanks for your help!
