Sending UDP packets via the internet and between processes?

I'm setting up two applications, a client and a server, that will
exchange some data back and forth. The server may be on the same
machine as the client, or it may not be, or there might be
multiple clients which may or may not be on the same machine.
Both applications will be running other code and I'd like them to
be able to access a list of received packets rather than waiting
for them to come in.
What do I need to do to set this up? This is as far as I've got:
ushort port = 3000;
auto sender = new UdpSocket();
sender.blocking = false;
auto address = new InternetAddress(port);
sender.bind(address);
ubyte[Packet.sizeof] bytes;
Packet* packet = cast(Packet*)bytes.ptr;
//not sure how to convert a struct to big endian easily?
sender.send(bytes);
I'm not really sure how to receive sent bytes or if I need to put
in ip addresses to make it work online? I've looked at a couple
of examples and I've gotten some html to work by accessing a
localhost port, but I've always struggled with networking, so if
someone can help explain how I'm meant to connect sockets that
may be online or on the same machine... that would be a big help!
