FAQs of Ubuntu Lists Network Interfaces: A Comprehensive Guide

To list all network interfaces on your Ubuntu system, you can use the ip addr or ifconfig( need to install net-tools for this) command in the terminal. This will display detailed information about all network interfaces, including their status, IP address, and more.

Both ifconfig and IP commands are used to configure and display network interface information, but ifconfig is aged and disapproved. The IP command provides further features and is the recommended mileage for ultramodern Linux systems, including Ubuntu.

The lo interface, also known as the loopback interface, is a special network interface used by the system for internal communication. It's used for troubleshooting and network testing.

You can enable or turn off a specific network interface in Ubuntu using the sudo if over(interface_name) command to help and sudo if down(interface_name) to turn it off. Replace(interface_name) with the name of the network interface you want to turn on or off.
