How do I change my network mask in Linux?

To change your IP address on Linux, use the “ifconfig” command followed by the name of your network interface and the new IP address to be changed on your computer. To assign the subnet mask, you can either add a “netmask” clause followed by the subnet mask or use the CIDR notation directly.
