I have noticed that some non gateway devices offer a capability of accessing their web interface by a hostname.
Here is a reference for Hass.io. The question is not locked to a specific vendor it's just an example I found.
In short, the instructions say:
- install the image to your Raspberry Pi
- connect it to your WiFi
- web interface is accessible at
My question is why can some other PC in the same subnet resolve
hassio.local to an IP address.
/etc/hosts on that PC and the DNS server is defined by the router, nothing that the newly introduced hassio device could influence.
Is there another resolving mechanism I'm unaware about?
