One thing its used for is media streaming.
My understanding of how it works (which might be correct or not) is you have
a host who might be streaming video or music, with say 1000 listeners,
rather than that 1 host sending data to 1000 different clients it uses
multicasting, which means all the clients have a multicast address (which is
IP range 224.x.x.x-239.x.x.x), then the host only has to send a media strean
to 1 multicast address, rather than 1000 normal addresses.
At least thats my simplistic understanding of it...I need to study it more,
firstly because I think I got most of the questions in the exam on multicast
wrong, and secondly because it might come in very useful in the future
(especially if you can use it to deploy drive images, like LnkWizard)
