In this blog post, we will show you how to assign static ip address on Debian 12.

In the world of Linux, Debian remains one of the most popular distributions, known for its stability and versatility. One essential aspect of managing a Linux system is configuring network settings. Whether you’re setting up a server or just want a consistent IP address for your desktop, assigning a static IP address on Debian 12 can be a crucial task.


  • Pre-Installed Debian 12
  • Sudo User with admin rights

There are different methods through we can assign static ip address on Debian 12.

Method1: Assign Static IP Address on Debian 12 Using GUI

Login to your Debian Desktop environment, From Activity –> Search Settings –> Choose Network


Click on Wired Settings and then we will get the following window,


Note: To disable IPv6, go to IPv6 tab and choose ‘Disable’ option

Click on IPv4 Tab


Above window shows that Automatic DHCP is enabled, so to Assign Static IP choose ‘Manual’ and then specify the IP details like IP address, netmask, gateway and dns server IP.

Important Note: To Specify the dns server IP first disable the automatic dns IP by toggling it.


Click on Apply to save the changes.

Now, disable and enable the interface by toggling it so that new IP address is mapped to the Interface.


Now again click on wired settings to verify whether the new static ip address is assigned or not.


Perfect, above confirms that new static IP address is assigned successfully.

Method2: Assign Static IP Address on Debian 12 From Command Line

Open the terminal, check your current network configuration. You can do this by running the following ip command,

$ ip add show


This will display a list of network interfaces on your system. Note down the name of the interface you want to assign a static IP address to (typically, it’s ‘enp0s3‘ for Ethernet).

Next, run nmcli command to get connection name,

$ nmcli connection


Once we get the connection name, run below nmcli command to assign static ipv4 address,


$ nmcli con mod  ‘connection-name’ ipv4.address  <IP-Address>

$ sudo nmcli connection modify 'Wired connection 1' ipv4.address

Set the gateway by running below

$ sudo nmcli connection modify 'Wired connection 1' ipv4.gateway

Change Configuration from DHCP to Manual , so that IP will be static and persistent, run

$ sudo nmcli connection modify 'Wired connection 1' ipv4.method manual

Set the DNS server IP by running below command,

$ sudo nmcli connection modify 'Wired connection 1' ipv4.dns ''

Disable and enable the connection so that above changes come into the effect.

$ sudo nmcli connection down 'Wired connection 1'
$ sudo nmcli connection up 'Wired connection 1'


Now run IP Command to check IP address,

$ ip add show enp0s3

Output of above commands would look like below:


Perfect, above output confirms that static IP address has been assigned successfully on enp0s3 interface.

Assign Static IP Address on Minimal Installed Debian 12

Whenever we install minimal Debian 12 then we will have only the CLI console and don’t have any nmcli utility. So, to assin static ip address we must edit the file ‘/etc/network/interfaces’.

$ cat /etc/network/interfaces


Edit the file and set the static IP address as shown below,

$ sudo vi /etc/network/interfaces

Replace the line ‘allow-htplug enp0s3’ with ‘auto enp0s3‘ and change dhcp parameter to static.  Below is my sample file, change interface name and ip details as per your environment.

auto enp0s3
iface enp0s3 inet static

save & close the file.


To make above changes into the effect the restart the network service

$ sudo systemctl restart networking.service

Now, run ip command to verify the ip address,

$ ip add show
