An Internet socket, naming an IPv4 address and UDP port. On output, the
address is always in numeric dotted-quad form, and the port is given as
a plain number. On input, DNS hostnames and symbolic port names are
-permitted. Name resolution does not block the main server, but will
-block the requesting client, unless the command is run in the background.
