Communicating within a subnet.

[spsingh]

I have an application that intends to communicate with other instances of the application running in the subnet. I do not want a dedicated server application to act as a middleman. What is the best approach for this?
I think multicast and broadcast are a few candidates, but I do not know how to go about it. I am stuck at the point that how Do I determine the multicast address to send to. What if the target netwrok does not have any IP address in the multicast adress range (224.0.0.1).

Hi,
Unless there is a restriction on your network and IPs, you can use a private network to get this setup you need.

Usually, 10.1.4.x is the valid range of IPs. You can connect through a hub without needing to go through a server first. However, this network will not be accessible from outside, hence the private network.
