IP address configuration

I am creating a new machine but I don’t know or it won’t let me configure the machine’s IP address to be static through the dhcp dhclient.conf file. I have returned to eth0 and removed netplan but it still doesn’t work. I don’t know if it should be done this way but I need help.

It is important to define the OS you are using on your machine. Different OS have different ways of setting it up and different tools (e.g. OpenSuse has Wicked).

If it is ParrotOS it might be helpful to check here: https://www.youtube.com/watch?v=WpmpshwnCVc
