UDP Broadcast across VLANs

[Ahmed Sayed]

But I don't understand the IP in multicast group property in both component client/server, for example my IP at home in the local network is: 192.168.1.x why does the multi cast IP starts with 224? I can't even get it to work on the same vlan network between my machine and a VM both on the same network, like PC1: 192.168.1.10 PC2: 192.168.1.20 what is the proper IP to use in multi cast group in order to make send data?
