omitted, the value of 6666 is used. If the env var doesn't exist, the
broadcast address and port 6666 are used. If it is set to an IP
address of 0 (or 0.0.0.0) then no messages are sent to the network.
+The source / listening port can be configured separately by setting

+configured by setting the 'ncoutport' environment variable.
For example, if your server IP is 192.168.1.1, you could use:
