Create additional IP address in a separate network namespace

I’m running Ubuntu 18.04, Linux kernel 5.4.0. My laptop has local IP address 192.168.0.130:

$ sudo ip addr show dev wlp2s0
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 7c:2a:31:09:3e:e0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.130/24 brd 192.168.0.255 scope global dynamic noprefixroute wlp2s0
       valid_lft 2782sec preferred_lft 2782sec
    inet6 fe80::b375:a43d:9705:556a/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

The routing table looks like:

$ sudo ip route
default via 192.168.0.1 dev wlp2s0 proto dhcp metric 600 
169.254.0.0/16 dev wlp2s0 scope link metric 1000 
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown 
192.168.0.0/24 dev wlp2s0 proto kernel scope link src 192.168.0.130 metric 600 

I want to use an additional IP address visible for other hosts on the local network (e.g. 192.168.0.12). It works like this:

$ sudo ip addr add 192.168.0.95/24 dev wlp2s0
$ ssh 192.168.0.12 ping 192.168.0.95
...
64 bytes from 192.168.0.95: ...
(works)
^C
$ sudo ip addr del 192.168.0.95/24 dev wlp2s0

Now, I want to move this IP address to a separate network namespace called net5, like this:

$ sudo ip netns add net5
$ sudo ip link add link wlp2s0 name net5in type macvlan
$ sudo ip link set net5in netns net5
$ sudo ip netns exec net5 ip addr add 192.168.0.95/24 brd + dev net5in
$ sudo ip netns exec net5 ip link set net5in up
$ ssh 192.168.0.12 ping 192.168.0.95
...
From 192.168.0.95: ... Destination Host Unreachable
(doesn't work)
^C
$ sudo ip netns add net5

How can this be fixed so that the ping above works?

I was following these tutorials:

• https://serverfault.com/a/900666 : ping doesn’t work.
• https://blog.oddbit.com/post/2018-03-12-using-docker-macvlan-networks/ recommends docker network create, but I don’t have Docker, and I want to make it work without Docker.
• https://sreeninet.wordpress.com/2016/05/29/macvlan-and-ipvlan/ doesn’t explain how to set up IP addresse.
• https://docs.oracle.com/cd/E37670_01/E37355/html/ol_mcvnbr_lxc.html doesn’t show what setup commands to run.

Updates:

• I was able to make it work by using type ipvlan mode l2 instead of type macvlan above. A local ping still doesn’t work, but — as I understand — that’s expected for macvlan and ipvlan.

sudo ip link del hostnet ||:
sudo ip link add hostnet link wlp2s0 type ipvlan mode l2
sudo ip addr add 192.168.0.90/32 brd + dev hostnet
sudo ip link set hostnet up  # `ip route add' below needs it.

for I in 91 92 93; do
sudo ip netns del net"$I" && sleep .5 ||:
sudo ip netns add net"$I"
sudo ip netns exec net$I ip link set lo up
sudo ip link add link wlp2s0 name net"$I"in type ipvlan mode l2
sudo ip link set net"$I"in netns net"$I"
sudo ip netns exec net"$I" ip addr add 192.168.0."$I"/24 brd + dev net"$I"in
sudo ip netns exec net"$I" ip link set net"$I"in up
sudo ip netns exec net"$I" ip route add default via 192.168.0.1
sudo ip route add 192.168.0."$I"/32 dev hostnet
done
