Hi all, I have this network: 10.1.20.0 - 10.1.23.0 /22 Broadcast 10.1.23.255
Say I have a machine with IP: 192.168.1.1 Now, I want to create virtual IP on it with ip command:
1. Is this ok? ip addr add 10.1.22.100/22 dev eth0:1
2. Should I define the broadcast too in the above command? If I don't define it, will the above command means the broadcast would be 10.1.25.255?
Thank you. Fajar.

By specifying /22 as the subnet mask, you're implicitly specifying the broadcast address. You don't need to specify it, manually.
However, based on a CIDR notation of /22 (which is a subnet mask of 255.255.252.0), the broadcast will actually be 10.1.23.255.

This is only a temporary solution, until network system is reset. If you want permanent IP you must create Virtual IP via either network file or NetworkManager GUI.

ip a a 10.1.22.100/22 dev eth0
that will do

you can skip the broadcast if you want
