So I am starting my studies on multicast. This is a technology that I have never configured so I am learning it for the first time. I have a few questions about the basics of multicast. I also have listed a few things I believe to be true about multicast based on my studies so far.
1. The 188.8.131.52/24 is said to be used locally only and not to be forwarded by multicast routers. Can someone explain this more.
2. The way I understand it, multicast is used for one to many and if clients join a multicast stream, doesn't that imply that the stream is live?
3. Is this a good example of multicast-- my cable box would be a client configured with a multicast group address and when I go to change the channel on my cable box, that channel that I change to is configured with a different multicast group. When I change the channel I join that group based on the channels multicast group. Is the cable box in this example a Client or receiver? And what would the name be for the cable modem? Also what multicast addresses would be used in this example-- something public or some private range?
So I am really trying to get a good feel for a real would example of multicast. Once I have that I can build on it.
