We use an environment variable 'ncip' to set the IP address and the
port of the destination. The format is <ip_addr>:<port>. If <port> is
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.
