-=item B<tcp:>I<ip>:I<port>
+=item I<node>
-Connect to the given tcp I<port> on I<ip>, where I<ip> is IPv4 address
-of OVS DB server which is listening on TCP I<port> for incoming
-JSON-RPC client connection.
+The I<node> argument of the address can be either network hostname, IPv4
+numbers-and-dots notation or IPv6 hexadecimal string format. In case of Unix
+domain socket, the "I<unix:>file" format should be used, where I<file> is
+the full name of OVS DB Unix domain socket.
-=item B<unix:>I<file>
+=item I<service>
-Connect to the unix domain server socket named I<file> which is
-used by OVS DB for incoming JSON-RPC client connection.
+The I<service> argument of the address specifies the service name used to
+connect to OVS DB. See L<services(5)> for more details. This argument is
+skipped if Unix domain address is used.
