A docker container’s IP usage heavily (entirely) depends on how the container’s networking is defined by the host machine. And in an overwhelming amount of cases, that host networking will be a “here’s a device-local subnet your containers can join to”, so no, a Docker container won’t by default “get it’s own IP address” (colloquially, “its own IP address” would refer to a device getting a LAN-local address assigned to it from the local gateway/DHCP server), at least not one other devices on the network can access.
Also claiming that “nothing else will use port 80” is a gross over-simplification.
The move to port 80/443 on HAOS makes sense as it simplifies setup for total beginners.






Yep. it’s essentially a ridiculous, yet somehow legal racket.
