How to add additional static IP’s
Ubuntu 17 / 18 / 20
From Ubuntu 17.10 and on the /etc/network/interfaces file is no longer used. It uses Netplan. This configuration file is found at /etc/netplan. Now we will edit the configuration file, we recommend to use ‘nano’ to edit the file:
| nano /etc/netplan/01-netcfg.yaml |
Adding a static IP in the netplan file is easier than you might think. Just add a comma after the current address and add the new one. We have highlighted this.
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
ens3:
dhcp4: no
dhcp6: no
addresses: [192.168.1.50/24,192.168.1.51/24]
gateway4: 192.168.0.1
nameservers:
addresses: [93.190.136.10,217.23.0.121]

To apply the new configuration, apply with the following in the command line:
| netplan apply |
If you want to add more IP addresses, simply add this after the one that was just added and separate by using a comma. Do not add any spaces in between.
Note: if you receive an error, please check the configuration as netplan is very space and character-sensitive. If you don’t use the exact amount of spaces in the above example it will fail.
