All things related to multicast

hi,


ok...curiosity is a powerful beast.  I traced some local systems that were
a member....expecting to be confronted by some evil root kit or such ..  ;-)


'Spotify' is the App that uses that group. when firing up Spotify you join
the following:

239.192.83.80           1:0:5e:40:53:50         en0
239.255.255.250         1:0:5e:7f:ff:fa         en0

(netstat -g on the OSX machine..... and looking at group membership IGMP list
on the router)
