How to Check the IP Address on a Debian Server


Knowing the IP address of your Debian server is essential for managing and troubleshooting your network. Whether you’re setting up a web server, SSH access, or simply monitoring connectivity, here are the steps to find your server’s IP address.

1. Using the ip Command

The ip command is the most modern and commonly used tool to retrieve IP address information. Run the following command:

ip addr show

 Using the ip Command

Look for the section corresponding to your network interface (e.g., eth0, ens33, or wlan0). The IP address will be listed under the inet field. For example:

2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    inet 192.168.1.100/24 brd 192.168.1.255 scope global dynamic ens33

Using the ip Command example

Here, the IP address is 192.168.1.100.


2. Using the ifconfig Command

The ifconfig command is a traditional method for viewing network configurations. Although it’s deprecated in newer Debian versions, you can still install and use it:

sudo apt install net-tools
ifconfig

Using the ifconfig Command

The IP address will be listed next to the inet field under the relevant network interface.


3. Using hostname -I

For a quick and simple way to view the IP address, use:

hostname -I

Using hostname -I

This will display your server’s IP address(es) in a single line, separated by spaces.


4. Viewing Network Configuration Files

You can also check the IP address by viewing network configuration files, especially if your server uses static IP settings:

cat /etc/network/interfaces

Viewing Network Configuration Files

Look for lines starting with address, which will indicate the IP address.

How do I find the public IP address of my server?

You can use an online service like curl to fetch your public IP address:

curl ifconfig.me
What is the difference between private and public IP addresses?

Private IPs are used within a local network, while public IPs are used to connect to the internet. Private IPs usually start with 192.168.x.x or 10.x.x.x.

How do I make my IP address static on Debian?

Edit the /etc/network/interfaces file or configure your network manager. Define the address, netmask, gateway, and dns-nameservers.

Yes, if you’re using a desktop environment, navigate to Settings > Network to view your IP address.
