linux static ip

Identify your network interface using ip a. 2. Determine your network manager by checking for Netplan, NetworkManager, ifupdown, or systemd-networkd. 3. Configure the static IP via Netplan (edit /etc/netplan/*.yaml and apply with sudo netplan apply), or ifupdown (edit /etc/network/interfaces and restart networking), or NetworkManager (use nmcli to modify connection settings), or systemd-networkd (create a .network file and restart the service). 4. Verify with ip a, ping the gateway and internet, and test DNS resolution, ensuring all responses are successful.

How to Configure Static IP Addressing on Linux

Setting a static IP address on Linux gives you full control over your network configuration—useful for servers, network devices, or when you need consistent network settings. While the exact method depends on your Linux distribution and network management tool, here’s how to do it correctly across common setups.

How to Configure Static IP Addressing on Linux

1. Identify Your Network Interface

Before making changes, find out the name of your network interface:

ip a

Look for your active interface—common names include eth0, ens33, enp0s3, or wlan0 for Wi-Fi. You’ll need this name for configuration.

2. Check Which Network Manager You're Using

Modern Linux systems use one of several network configuration systems:

  • Traditional method: Editing /etc/network/interfaces (Debian/Ubuntu with ifupdown)
  • Netplan: Default on Ubuntu 17.10 and later
  • NetworkManager: Common on desktop systems (Fedora, RHEL, CentOS, some Ubuntu)
  • systemd-networkd: Used in minimal or server setups

Use this to determine your system:

How to Configure Static IP Addressing on Linux
ls /etc/netplan/           # If files exist, you're likely using Netplan
systemctl is-active NetworkManager  # Check if NetworkManager is running
cat /etc/network/interfaces # Check for ifupdown config

3. Configure Static IP Based on Your System

Option A: Netplan (Ubuntu 18.04 )

Netplan uses YAML files in /etc/netplan/. Edit the main config:

sudo nano /etc/netplan/01-netcfg.yaml

Example configuration for a static IP:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: no
      addresses:
        - 192.168.1.100/24
      gateway4: 192.168.1.1
      nameservers:
        addresses: [8.8.8.8, 1.1.1.1]

Apply changes:

sudo netplan apply

? If you get errors, test with sudo netplan --debug apply to see what's wrong.


Option B: /etc/network/interfaces (Debian with ifupdown)

Used on older Debian or Ubuntu systems. Edit the file:

sudo nano /etc/network/interfaces

Modify the interface section:

auto enp0s3
iface enp0s3 inet static
    address 192.168.1.100
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 8.8.8.8 1.1.1.1

Restart networking:

sudo systemctl restart networking

Option C: NetworkManager (via nmcli)

If you're on a desktop using NetworkManager, use nmcli:

First, list your connection:

nmcli connection show

Then modify it (replace YourConnectionName and interface):

nmcli connection modify "YourConnectionName" ipv4.addresses 192.168.1.100/24
nmcli connection modify "YourConnectionName" ipv4.gateway 192.168.1.1
nmcli connection modify "YourConnectionName" ipv4.dns "8.8.8.8 1.1.1.1"
nmcli connection modify "YourConnectionName" ipv4.method manual

Restart the connection:

nmcli connection down "YourConnectionName"
nmcli connection up "YourConnectionName"

Option D: systemd-networkd (Minimal or Custom Systems)

Create or edit a .network file:

sudo nano /etc/systemd/network/10-static-eth0.network

Add:

[Match]
Name=enp0s3

[Network]
Address=192.168.1.100/24
Gateway=192.168.1.1
DNS=8.8.8.8
DNS=1.1.1.1

Enable and restart:

sudo systemctl enable systemd-networkd
sudo systemctl restart systemd-networkd

4. Verify Your Configuration

After applying changes:

  • Check IP: ip a
  • Test gateway: ping 192.168.1.1
  • Test internet: ping google.com
  • Check DNS: nslookup google.com

Make sure everything responds.


Final Notes

  • Always keep a backup SSH session open when testing remotely—mistakes can disconnect you.
  • Use IP addresses that don’t conflict with your router’s DHCP range.
  • The netmask (e.g., /24) determines your network size—match it to your local network.

Basically, pick the method that matches your system and stick to correct syntax—especially with YAML in Netplan. Once set, your machine will always use the same IP.
