Host UDP Multicast Online, possible?

问题

I have made a server that uses UDP multicast sockets.

I am able to run the server on my local host and try with as many clients as I want.

The problem is that i'm new to UDP and multicast and now I need to connect to another pc using the internet.

For example:

group = InetAddress.getByName(sendAdd);
buf = senddata.getBytes();
packet = new DatagramPacket(buf, buf.length, group, senderPort);

Is there anyway to host the UDP multicast server online? What InetAddress should I use in that case?

回答1:

The solution I found is that there is no way of hosting a multicast server online. Rather than simulating a local network using f.e "hamachi" or any other software.
