# Command: HOST-ADDRESS

Format HOST-ADDRESS o1.o2.o3.o4

Example: `HOST-ADDRESS 192.168.2.2`

Sets the IP address of the 'host' to 'o1.o2.o3.o4'. The 'host' is the system to which the ROVL sends output messages, unless otherwise configured. This can be a broadcast address like 255.255.255.255, but you may not want yo use braodcast addresses on a Wi-FI network because it may bog down the network.
