again not on your side, I tried in Pharo and they introduced a class SocketAddress.
You have to send that instance the message hostNumber to get the IP-Address as .... oops ... a String. I surely didn't expect that!
What makes it worse, is that my code works though I hand an Array as the IP address to Socket. So my best guess is you go to the Pharo list and ask about the proper way to set up a UDP (or TCP) connection.
I could tell you how to pick the bytes out of SocketAddress but this is Smalltalk after all. There must be a high level way.
Sorry for no better reply,
Herbert
