macvlan
A Docker network mode that gives a container its own MAC address and IP on your physical LAN.
macvlan is useful when a container needs to appear as a real device on your network — for example Pi-hole listening on port 53 without conflicting with the host. It has quirks, like the host being unable to reach the container directly.
