How to Configure a Static IP Address on Debian 13

To configure a static IP address on Debian 13, follow the steps below:

Step 1 : Update the package list to make sure the system is up to date:

sudo apt update

Step 2 : List all network interfaces and identify the Ethernet interface name:

ip a

Common interface names may include eth0, ens33, or enp0s3.

Step 3 : Edit the network configuration file:

sudo nano /etc/network/interfaces

Add or modify the configuration as shown below (adjust values to match your network):

auto ens18
iface ens18 inet static
    address 192.168.1.150
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 8.8.8.8 8.8.4.4

Replace ens18 and the IP information with your actual interface name and network settings.

Save the file and exit.

Step 4 : Apply the changes by restarting the networking service:

sudo systemctl restart networking

Step 5 : Check the assigned IP address:

ip a

Step 6 : Verify the configuration by checking network connectivity:

ping google.com
