Re: About Multicast

Hosts that are interested in receiving data flowing to a particular multicast group must join the group using Internet Group Management Protocol (IGMP). Hosts must be a member of the group to receive the data stream.

Here's a link to more information on multicasting:

Check out the "IP Multicast Overview" link in particular.

Hope this helps.
