Configuring IP Addresses in Ubuntu

Configuring IP Addresses in Ubuntu: Quick Reference

Networking in Ubuntu has always been frustrating and inconsistent for me. Hope this helps you as much as it helps me.

1. /etc/NetPlan/<any file>:

	
				#### This file commonly shows up as '00-installer-config.yaml'

				#### but it may also show up starting with a '50' or something

				#### else. If no such file exists, try a different configuration

				#### file.

				#### NOTE: Because YAML is YAML, indentation must be spaces and

				#### must be precise.

				network:

				  ethernets:

				    eth0:

				      addresses:

				        - 10.2.3.4/24

				      nameservers:

				        addresses: [10.2.3.2,8.8.8.8]

				      routes:

				        - to: default

				          via: 10.2.3.1

				    # DHCP Example
	
				    eth1:

				      dhcp4: true

				  version: 2

				#### Apply your configuration using 'sudo netplan apply'.

2. /etc/network/interfaces:

	
				#### Can also put these in files in /etc/network/interfaces.d/

				auto iface eth1

3. ip

				
				#### Note: I don't recommend using ip. See the words for more.

				sudo ip link set dev eth0 address 10.2.3.4/24

				sudo ip link set dev eth1 address dhcp
