+                       para_server listens on a TCP socket for incoming connections from
+                       para_client or para_audiod. This option controls on which addresses
+                       the server should listen. If the option is not given, the server
+                       listens on all local addresses (INADDR_ANY for IPv4 addresses,
+                       IN6ADDR_ANY_INIT for IPv6 addresses).
+
+                       The argument specifies an IPv4 or an IPv6 address, either a numerical
+                       network address (for IPv4, numbers-and-dots notation as supported
+                       by inet_aton(3); for IPv6, hexadecimal string format as supported
+                       by inet_pton(3)), or a network hostname, whose network addresses is
+                       looked up and resolved. The address can optionally include a port
+                       number. For addresses for which no port number is given, the argument
+                       of the --port option (see below) is implied.
+
+                       This option may be given multiple times. The server will then listen
+                       on each of the specified addresses.
+

-                       para_server listens on this TCP port for incoming connections
-                       from clients such as para_client. If the default port is changed,
-                       the corresponding option of para_client must be used to connect
-                       to para_server.
+                       This option applies only to addresses given to --listen-address
+                       (see above) which do no include a port number. If the default port
+                       is changed, the corresponding option of para_client must be used to
