A note on network device addresses

[twostar]

I've just discovered, through trial and error, that at least MQTT servers don't need to be specified by IP address but can also be specified by DNS name.  So in the Protocol -> General page, for the MQTT Broker Address, you can enter mqtt://mosquitto.lan instead of mqtt://192.168.1.200 (or whatever) and it'll work fine.  This is quite convenient since you no longer have to hardcode in IP addresses for everything.
