- Host configuration is two interfacces:
$ ip a show eth0
eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:50:56:2b:29:40 brd ff:ff:ff:ff:ff:ff
inet 172.16.86.151/24 brd 172.16.86.255 scope global eth0
$ ip a show eth1
eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:50:56:39:45:2e brd ff:ff:ff:ff:ff:ff
inet 192.168.1.251/24 brd 192.168.1.255 scope global eth1
$ ip route
default via 172.16.86.2 dev eth0

- The first two networks created are isolated since no parent is specified.
- The second two can reach externally as they are using the host interfaces listed above. Those two interfaces have gateways of
192.168.1.1 and 172.16.86.2 which are spcified in the docker network create commands below.
# Nil Parent Ipvlan (Containers are isolated if no parent is specified)
