Unlike TCP, UDP does not establish a connection. By default you will not
receive any network errors on a UDP socket. You have to call connect()
on the socket in order to receive (ICMP) error messages, but this has
other implications.

With UDP it is more common to rely on application layer error messages
and/or timeouts.
