Normally, with UDP servers, you'd use socket.recvfrom() to read the data
from the client and get its address.

https://docs.python.org/3/library/socket.html#socket.socket.recvfrom

But it doesn't seem like pythonosc supplies the client's address to the
dispatcher.

It's not uncommon for OSC software, that you have to specify client (a)
address(es) in the server as well, since OSC, commonly using UDP as a
transport, is only uni-directional, so to get bi-directional
communication, every participant in an OSC communication has to be a
server and a client.

If you don't need a pure-Python library, I'd look at python-liblo.
