Question valid multicast ip addressess


actually my question is about the network itself and not bind to linux, but what do you expect on me? to post that on a windows network forum? I just sayin
OK here's the problem

I wanna implement some live streaming on the internet. the multicast ip addressing stack telling me some part of the multicast ip addresses are reserved for internet. So what I'm gonna do? by some from my data center provider?
please help, it's critical for me.

maybe speaking about valid on multicast addresses was not so right, maybe its just a issue inside the data center network, I don't know

Multicast routing is a completely different technology from IP routing. If you want to multicast to your own internal network, you need to configure multicast routing on your routers. If you want to multicast to the internet you will need to talk to your service provider about a connection to the multicast backbone (MBONE).

Are you sure you need to multicast? You can stream via different protocols, unicast UDP etc.

To answer your actual question, you can use any multicast network address you want internally, but 239.*.*.* is reserved for internal use so technically speaking you should use one of these. To multicast to the internet you need to be assigned addressed in the 224.0.1.x to 238.255.255.255 range.

thank you for the reply, of course I need it on the internet, and because those are live, it's better to be multicast. (udp over multicast)
any way I've configured many internal multicast networks and I used the internal as well. The MBONE was a new key word I got and as I get I have to ask the service provider for the MBONE and they would give me an ip address in 224.0.1.x to 238.255.255.255 range. is it so?
If so, what if the routers in internet for some users don't support multicast? what would happen then?

This is your problem is that the internet does not really support multicast, in effect anyone wanting to multicast over the internet needs to basically open a tunnel to the multicast backbone, so its a fairly technical process. That's why its not really the sort of thing that you would offer to random visitors.
