The first task anyone would do after installing Ubuntu is setting an IP address to a system to connect to the network/internet. If the Wi-Fi router, ISP, or network doesn’t provide DHCP services, you must manually assign IP addresses.
Here, we will see how to set a static IP Address on Ubuntu 22.04, using,
You can use any method to set a static IP address on Ubuntu 22.04.
Find Network Interfaces on Ubuntu 22.04
You can run any of the below commands in a terminal to get a list of network interfaces available on the system.
sudo ifconfig -a
OR
sudo ip a
The output of the ifconfig command on a desktop:
enp0s3: flags=4163mtu 1500 ether 08:00:27:36:34:ae txqueuelen 1000 (Ethernet) RX packets 226971 bytes 327928478 (312.7 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 60417 bytes 4869126 (4.6 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1 (Local Loopback) RX packets 4714 bytes 6158753 (5.8 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4714 bytes 6158753 (5.8 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
The output of the ifconfig command on a laptop:
lo: flags=73mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 188 bytes 13462 (13.4 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 188 bytes 13462 (13.4 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlo1: flags=4163 mtu 1500 ether 7c:8b:ca:0d:69:b6 txqueuelen 1000 (Ethernet) RX packets 972 bytes 346365 (346.3 KB) RX errors 0 dropped 465 overruns 0 frame 0 TX packets 426 bytes 66875 (66.8 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Here, we will see how to configure a static IP for enp0s3 (Wired) / wl01 (Wi-Fi).
IP Address: 192.168.0.10
Netmask: 255.255.255.0
Gateway: 192.168.0.1
DNS Server 1: 192.168.0.1
DNS Server 2: 8.8.8.8
Domain Name: holhol24.local
Set Static IP Address on Ubuntu 22.04 Desktop
1. Using GNOME Network Manager
Using the GNOME network control center to set a static IP address on In Ubuntu 22.04 desktop is straightforward.
Set IP for Wired Interface using GNOME
Open the Gnome control center using the gnome-control-center network command or go to Activities >> Settings >> Network.
Click on the gear icon on the Wired interface page and then IPv4 tab >> Manual >> Enter IP address, Netmask, Gateway, DNS (Toggle to disable Automatic DNS configuration) >> Apply.
Finally, use the toggle in the Network page to disable and enable the network interface to apply the IP address.
Set IP Address for Wi-Fi using GNOME
Open the Gnome control center using the gnome-control-center wifi command or go to Activities >> Settings >> Wi-Fi.
Click on your Wifi router name and then enter the router’s password to connect. Your laptop will automatically receive an IP address from a Wi-Fi router with a built-in DHCP service on a successful connection.
To assign a static IP address or Wi-Fi interface, click on the gear icon on the Wi-Fi interface page and then IPv4 tab >> Manual >> Enter IP address, Netmask, Gateway, DNS (Toggle to disable Automatic DNS configuration) >> Apply.
Finally, disable and enable the Wi-Fi interface to apply the IP address.
2. Using Netplan
Netplan is a utility for easily configuring networking on a Ubuntu system. It reads the configuration files .yaml present in the /etc/netplan directory.
This utility supports both networkd and Network Manager as backends. However, using Network Manager as a backend renderer: NetworkManager is recommended for the Ubuntu desktop. The remaining configurations are the same as that of the networkd.
3. Using NetworkManager CLI
Set IP for Wired Interface using nmcli
First, let us list the available network connections.
nmcli connection show
Output:
NAME UUID TYPE DEVICE Wired connection 1 db3b0cfc-d875-3a71-86c4-626adfc5834a ethernet enp0s3
Then, configure static IP address to wired interface.
sudo nmcli con mod "Wired connection 1" ipv4.addresses 192.168.0.10/24 sudo nmcli con mod "Wired connection 1" ipv4.gateway 192.168.0.1 sudo nmcli con mod "Wired connection 1" ipv4.dns "192.168.0.1","8.8.8.8" sudo nmcli con mod "Wired connection 1" ipv4.method manual sudo nmcli con mod "Wired connection 1" ipv6.method disabled
Finally, run the below commands to apply the IP address.
sudo nmcli con down "Wired connection 1" && sudo nmcli con up "Wired connection 1"
Set IP Address for Wi-Fi using nmcli
First, list the available Wi-Fi access points using the below command.
nmcli device wifi
Output:
IN-USE BSSID SSID MODE CHAN RATE SIGNAL BARS SECURITY
BA:DD:71:A3:D9:A4 Raj Infra 6 270 Mbit/s 100 ▂▄▆█ WPA2
Next, connect to the Wi-Fi access point.
nmcli device wifi connect Raj password MyPass ifname wlo1 name My-Wifi
And then, configure static IP address to Wi-Fi interface.
sudo nmcli con mod "My-Wifi" ipv4.addresses 192.168.0.10/24 sudo nmcli con mod "My-Wifi" ipv4.gateway 192.168.0.1 sudo nmcli con mod "My-Wifi" ipv4.dns 192.168.0.1 sudo nmcli con mod "My-Wifi" ipv4.method manual sudo nmcli con mod "My-Wifi" ipv6.method disabled
Finally, run the below commands to apply the IP address
sudo nmcli con down "My-Wifi" && sudo nmcli con up "My-Wifi"
Set Static IP Address Using NetPlan on Ubuntu 22.04 Server
Netplan is a network configuration utility that reads YAML files and generates all network configurations for the renderer tool (NetworkManager or networkd) to configure the network on a system.
Netplan configuration files are found in the /etc/netplan/ directory.
Remove any configuration files .yaml present in the /etc/netplan directory.
sudo rm -rf /etc/netplan/*
Set IP for Wired Interface using Netplan
Now, create a new netplan configuration for the wired network interface.
sudo nano /etc/netplan/01-wired-interface-1.yaml
Then, make changes to the below information and use it for your requirement.
network:
version: 2
renderer: networkd
ethernets:
enp0s3:
dhcp4: no
dhcp6: no
addresses:
- 192.168.0.10/24
routes:
- to: default
via: 192.168.0.1
nameservers:
addresses:
- 192.168.0.1
- 8.8.8.8
search:
- holhol24.local
And then generate the required configuration for the renderers.
sudo netplan generate
Finally, apply all network configurations and restart renderers.
sudo netplan apply
Set IP Address for Wi-Fi using Netplan
Wi-Fi Interface Name: wl01
Wireless Access Point Name: Raj
Wireless Access Point Password: MyPass
First, create a new netplan configuration for the wired network interface.
sudo nano /etc/netplan/01-wireless-interface-1.yaml
Then, make changes to the below information and use it for your requirement.
network:
version: 2
renderer: networkd
wifis:
wlo1:
dhcp4: no
dhcp6: no
addresses:
- 192.168.0.10/24
routes:
- to: default
via: 192.168.0.1
nameservers:
addresses:
- 192.168.0.10
- 8.8.8.8
search:
- holhol24.local
access-points:
Raj:
password: MyPass
And then generate the required configuration for the renderers.
sudo netplan generate
Finally, apply all network configurations and restart renderers.
sudo netplan apply
Verify Static IP Address on Ubuntu 22.04
Verify the static IP address using the below commands.
sudo ifconfig -a
OR
sudo ip a
Output:
enp0s3: flags=4163mtu 1500 inet 192.168.0.10 netmask 255.255.255.0 broadcast 192.168.0.255 ether 08:00:27:81:43:e1 txqueuelen 1000 (Ethernet) RX packets 1684 bytes 1211790 (1.2 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 1004 bytes 140357 (140.3 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 549 bytes 44488 (44.4 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 549 bytes 44488 (44.4 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Also, verify the DNS server’s entries.
sudo resolvectl status
Output:
Global
Protocols: -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
resolv.conf mode: stub
Link 2 (enp0s3)
Current Scopes: DNS

Current DNS Server: 192.168.0.1
DNS Servers: 192.168.0.1 8.8.8.8

Conclusion
That’s All.
