I think some brokerage firms broadcast out various news shows to the traders desktops via IP broadcast mechanisms. I assume they use Class D packets to carry the UDP packets.
What is the advantage of this over what I think the general approach is of using all one-bits in the rightmost part of the address not covered by the subnet mask? e.g. (192.168.0.255)
2 things I can think of: 1) That only broadcasts across a single lan segment. Big enterprises might want to do multi-cast to multiple segments at once. Think of those brokers sitting in a tall building with one lan segment per floor. 2) That gives you one broadcast address only and thus only one way of controlling how it gets forwarded at the network. I think routers / switches can be configured to forward specific Class D addresses and not others.
