If you’re new to Ubuntu server administration, you might be wondering how to get the IP address of your server. Fortunately, it’s easy to do, and we’re here to guide you through it!

🤔 What is an IP Address?

An IP address, or Internet Protocol address, is a unique numerical identifier assigned to every device connected to a computer network that uses the Internet Protocol for communication.

IP addresses serve two primary functions: network interface identification and location addressing. Network interface identification enables devices on a network to communicate with each other, while location addressing enables devices to communicate with other devices outside of their network.

To get started, open a terminal window and type the following command:

ifconfig

This will return information about all the network interfaces connected to your Ubuntu server, including their IP address. Look for the line that starts with “inet” and find the IP address next to it.

Method 2: Using ip addr

Command
