In my case:
on my macOS I running a minikube docker VM, and it host a docker bridge network.
check the b7cc12043647.
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
ada0c5109376 bridge bridge local
89afa32d0810 host host local
b7cc12043647 minikube bridge local
4f7dca22f5b6 none null local
I know docker bridge type network are attached to bridge0,
but my bridge0 is inactive.
