title: Home Assistant Mosquitto - What can I use as MQTT broker address?
body: <p>I'm using Home Assistant OS as a Virtualbox in Windows 10. I'm accessing it via homeassistant.local:8123. So I'm trying to configure my Mosquitto broker in Home Assistant. It wants to know my broker address. I'm guessing I need to use an ip. Where do I find this? Should I use localhost, 127.0.0.1, homeassistant.local or maybe an unused ip like 192.168.1.99 from my router?</p>
