Code Issues Proposed changes

Change the default multicast group range

Browse Source 
The 224.0.0.X range is a special range in multicast which acts like a
broadcast for non-IGMP traffic.

This patch changes the value of the multicast_group_range configuration
option to 225.0.0.X to avoid this special case.

See session "2.1.2.  Data Forwarding Rules" at
https://tools.ietf.org/html/rfc4541 for more information:

   2) Packets with a destination IP (DIP) address in the 224.0.0.X range
         which are not IGMP must be forwarded on all ports.
