how to multicast stream

My LAN is currently on 192.168.0.x subnet. I want to stream to everyong on the LAN. I always thought that 192.168.0.255 was a multicast IP. How would I stream a file to everyone? Just send it to the multicast IP?

Hello,
192.168.0.255 is the broadcast address. When you send data to it, it is sent to all computers on your lan.
Multicast addresses are the ones that begin with 224 --> 239 (from 224.0.0.0 to 239.255.255.255).
To stream to a multicast address, just send the stream to this address.
If your network hardware does not support igmp, multicast won't work as expected: either it will act as broadcast, either it won't work at all (in that case, stream to 192.168.0.255)

I tried using the broadcast but it is too slow on my LAN. The stream is too jumpy. When I sent to 224.0.0.0 nothing happened. For a multicast, more than one computer is getting sent the stream right? I am currently using Windows XP ICS as a router, and linux (slackware 9.1) to send the stream. How would I setup a multicast?

when you use multicast, the clients need to open the same IP.
unicast: send to an ip.
broadcast: send to all ip's in your network
multicast: sent to a multicast ip. your clients will need to tune into the same ip.
