Network Interfaces

Ubuntu uses Netplan to manage network interfaces. Netplan configuration files are stored in the /etc/netplan/ directory. By viewing the contents of the /etc/netplan/ directory, you can see the configuration files which are usually named *.yaml. The name often corresponds to the name of the network interface. To view the network interfaces on your system, run the following command:

ip link

To view the ip addresses for each network interface, run the following command:

ip addr
