Documented steps
Create a network without the -o parent option: docker network create -d ipvlan isolated1 (the subnet defaults to 172.18.0.0/16 when --subnet is omitted).
Recognize that leaving parent empty is identical to using --internal: both create a netlink dummy parent interface and fully isolate the network.
Confirm equivalence: docker network create -d ipvlan --subnet=192.168.10.0/24 isolated1 is the same isolation as docker network create -d ipvlan --subnet=192.168.11.0/24 --internal isolated2.
Open an interactive shell with docker run --net=isolated1 -it --rm alpine /bin/sh and confirm there is no path to the outside world.

Known gotchas
An isolated ipvlan network is for a fully internal cluster with no physical uplink; it behaves exactly like an --internal network.
Containers on the isolated network can reach each other by name but have no external route.
