People often forget the process for assigning an IP address (static or dynamic) from the Linux command line. Most actually feel too intimidated by the process to commit it to memory, but it’s actually very simple. Here’s how to get networking all the way up in a matter of seconds using just a few commands.Test by pinging someone.If you’re on a newer system, read on. Using ip and netplan You should start learning ip now, since it’s about to become common everywhere. Since ifconfig is being phased out, it’s time to get used to the new system. By default, Ubuntu 18.04 doesn’t use ifconfig anymore, and instead uses the new commands, ip and netplan.Permanence And finally, here’s how to make the change permanent (static) in various environments.

To get started, type ifconfig at the terminal prompt, and then hit Enter. This command lists all network interfaces on the system, so take note of the name of the interface for which you want to change the IP address. The following command changes the network interface named “eth0” to use the IP address 102.168.0.1, and assigns the subnet mask 255.255.255.0: If you run ifconfig again, you will see that your interface has now taken on the new settings you assigned to it.

Configure Static Addressing To find the networking information for each of your Linodes in your Linode Manager, click on the Linodes tab to the left of the page, select the Linode you’ll be configuring, then click on the Networking towards the top. You’ll see the following information for your Linode. Use this information to configure your Linode’s network settings as shown below. IPv4 and IPv6 addresses (both private and public) IPv4 gateway IPv6 gateway DNS resolvers (if you want to use Linode’s) Below are example configurations for the given Linux distribution. Edit the example files substituting the example IP addresses with those of your Linode, gateway and DNS nameservers. Depending on the amount of addresses you want to configure, not all lines will be necessary. Arch, CoreOS Container Linux Networking in these distributions is managed entirely by systemd.Note that NetworkManger in CentOS 7 and Fedora includes the tools nmtui and nmcli to modify network configurations. Those are additional options to set static addressing if you would prefer to not directly edit the network interface’s configuration file.NetworkManager is not installed by default, however a static configuration for CentOS 6 differs only slightly from CentOS 7 and Fedora.Though systemd-networkd and systemd-resolved are both present in Debian 8 and 9, they’re not enabled. You’ll need to use the section further above for Arch and Container Linux. For more information, see man ifup, man ifdown, man interfaces 5, man systemd-networkd and man systemd-resolved.In addition to directly editing the network configuration files shown below, you can also use YaST. See OpenSUSE’s networking documentation for more information.Apply the changes and reboot: sudo netplan applyYou’ll need to use the section further above for Arch and Container Linux.Can mix IPv4 and IPv6. Rebooting ensures that the new settings take effect without issues and that the all networking services reliably start again.

Additional IPv4 or IPv6 addresses can be requested by opening a support ticket and detailing your requirements. If you want to manually configure static addressing in your Linode’s operating system, this guide shows you how to do that. You will want to make these changes using Lish, so if a configuration error disconnects your SSH session, you won’t be locked out of a system that has no network access. General Information Interfaces Each Linode has only one virtual network interface, eth0, but depending on your distribution, additional IPs can be assigned to interface aliases (ex: eth0:1, eth0:2, etc.). Most outbound connections will originate from the IP assigned to eth0, but if you need server daemons to bind to a particular IP address or interface, you’ll need to specify that in the appropriate configuration files. Addressing The IP blocks available to your Linode are shown below. That gateway should be on the same network as the desired IP address. For example, if the address 198.51.100.5 is assigned to the interface eth0:3, you should use 198.51.100.1 as the gateway. A gateway should not be specified for private IP addresses. DNS Resolution Your DNS resolver addresses are listed under the Networking tab of the Linode detail page in the Cloud Manager, though of course you are free to use any resolvers you choose. Resolver options are usually set in the network interface’s configuration file. Disable Network Helper Our Network Helper tool is enabled by default for new Linodes. It automatically configures static IPv4 addresses, routing, and DNS on each bootup of your Linode. When manually setting static addressing, Network Helper must be disabled so it doesn’t overwrite your changes on the next reboot. You can disable Network Helper either globally for all of the Linodes on your account, or for individual Linodes, by following the Network Helper Settings section of our network helper guide.

In recent Ubuntu versions, we use Netplan utility to configure IP address. To configure IP address on recent Ubuntu distributions, refer the following link.

But it is entirely different in Command line mode. This step by step tutorial describes how to configure static IP address in Linux and Unix operating systems. The steps provided below are tested on CentOS 7 server, Ubuntu 16.04 server, Ubuntu 18.04 LTS server and desktop editions and FreeBSD 12. However, it should work on most RPM-based and DEB-based Linux systems and Unix flavors. Note: Here, I run all commands as root user. If you logged-in as normal user, just use 'sudo' in-front of each command. First, let us find the name of the network card. As you see in the above output, my wired network card name is enp0s3. Let us now configure a static IP address to this NIC. Add the IP address, subnet mask, gateway, and DNS server as shown below. Those are the important lines. Here, you might have noticed the number 0 (zero) after the line IPADDR. This indicates that this card has only one IP address. If you want to set more than one IP address (i.e virtual IP address), then add new lines - for example IPADDR1, IPADDR2 and set different IP addresses of your choice. Once you setup all details, save and close the file. Finally, Click OK to save the changes. Restart network service or reboot your system to take effect the changes.

Both command line and GUI methods have been discussed. IP addresses on Linux Systems in most cases are assigned by Dynamic Host Configuration Protocol (DHCP) servers. IP addresses assigned this way are dynamic which means that the IP address might change when you restart your Ubuntu system. It’s not necessary but it may happen. Dynamic IP is not an issue for normal desktop Linux users in most cases. It could become an issue if you have employed some special kind of networking between your computers. For example, you can share your keyboard and mouse between Ubuntu and Raspberry Pi. The configuration uses IP addresses of both system. If the IP address changes dynamically, then your setup won’t work. Another use case is with servers or remotely administered desktops. It is easier to set static addresses on those systems for connection stability and consistency between the users and applications. In this tutorial, I’ll show you how to set up static IP address on Ubuntu based Linux distributions. Let me show you the command line way first and then I’ll show the graphical way of doing it on desktop. Method 1: Assign static IP in Ubuntu using command line Note for desktop users: Use static IP only when you need it. Automatic IP saves you a lot of headache in handling network configuration.

This section will cover the simple network configuration changes needed to set a static IP network address for your server. For this section, the directions assume the configuration is for a node with only one interface (eth0) after a default installation. Please consult your OS documentation if you need assistance with these tasks.

Learn more Follow these steps to make the switch. When a system is a server or will be remotely administered, however, it is generally more convenient for these systems to have static addresses, providing stable and consistent connections with users and applications. Fortunately, the steps required to change a Linux system's IP address from dynamic to static are fairly easy, though they will be a little different depending on the distribution you are using. If it changes when the system restarts, it's clearly dynamically assigned, but even a dynamic address has some resistance to change. The best way is to look at the configuration file. More on this in the sections below. RHEL 8 To configure a static IP address on a Red Hat system, let's start by listing NetworkManager's connection.

The nmcli command shown below will list network connections and devices on the system. In this example, it's called ifcfg-Comtrend7BF9 (ifcfg- followed by the name of the connection). In addition, the IP address to be used has to be added to the file.In the output below, we see both a loopback and a public network interface listed. The device on your system may have a different name. This one that reflects the location of the hardware.Wrap-up Changing network settings should be done only when the changes will not affect current connections and you can back out the changes if needed. It's always a good idea to make a copy of any configuration file before you make changes. Giving your backup copy a predictable name such as interfaces.prev, interfaces.orig or interfaces- will make it a little easier to identify.

Step 1: Get the name of network interface and the default gateway The first thing you need to know is the name of the network interface for which you have to set up the static IP.Step 3: Edit Netplan configuration for assigning static IP Just for the sake of it, make a backup of your yaml file. Please make sure to use the correct yaml file name in the commands from here onward. If you use tab or incorrect indention, your changes won’t be saved. You should edit the file and make it look like this by providing the actual details of your IP address, gateway, interface name etc. network:Revert the changes and go back to dynamic IP If you don’t want to use the static IP address anymore, you can revert easily. If you have backed up the original yaml file, you can delete the new one and use the backup one. Otherwise, you can change the yaml file again and make it look like this: network:Go to the settings and look for network settings. Click the gear symbol adjacent to your network connection. Next, you should go to the IPv4 tab. Under the IPv4 Method section, click on Manual. In the Addresses section, enter the IP static IP address you want, netmask is usually 24 and you already know your gateway IP with the ip route command. You may also change the DNS server if you want. You can keep Routes section to Automatic. Once everything is done, click on Apply button. See, how easy it is to set a static IP address graphically.

Write For Us Privacy Terms Computers configured to be DHCP clients have no control over the settings it receives from the DHCP server, and the configuration is transparent to the computer’s user. This is typically found in an intranet setup meaning its only available local on the internal network. Either using the GUI network manager interface or via the command line Note: I have commented on lines that needs replacing or add incase your file contains more info. This implies that it automatically obtains an IP address from a router or a DHCP server in a network. However, there are certain instances that require configuration of a static IP. A good example is where you have a server, e.g a web server or an FTP server. You definitely don’t want its IP to keep changing once the DHCP lease time is over.

This will definitely cause loss of service once the IP changes. It can be installed both on RPM and Debian based distributions. Feel free to get back to us for any clarifications. I love experimenting with various distributions of Linux and keeping tabs on what's new in the Linux world. Setting a static IP address on your Ubuntu machine may be required in different situations, such as configuring port forwarding or running a media server on your network. Static DHCP or DHCP reservation is a feature found on most routers which makes the DHCP server to automatically assign the same IP address to a specific network device, every time the device requests an address from the DHCP server. This works by assigning a static IP to the device’s unique MAC address. The steps for configuring a DHCP reservation vary from router to router, and it’s advisable to consult the vendor’s documentation. Netplan uses configuration files in YAML syntax. To configure a network interface with Netplan, you need to create a YAML description for that interface, and Netplan will generate the required configuration files for your chosen renderer tool. Netplan currently supports two renderers NetworkManager and Systemd-networkd. NetworkManager is mostly used on Desktop machines while the Systemd-networkd is used on servers without a GUI. The first step is to identify the name of the ethernet interface you want to configure. To do so use the ip link command, as shown below: ip link The command will print a list of all the available network interfaces. In this case, the name of the interface is ens3: 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000The file may differ from setup to setup.Each Netplan Yaml file starts with the network key that has at least two required elements. The first required element is the version of the network configuration format, and the second one is the device type. The device type can be ethernets, bonds, bridges, or vlans.

The configuration above also includes the renderer type. Out of the box, if you installed Ubuntu in server mode, the renderer is configured to use networkd as the back end. Under the device’s type (in this case ethernets ), you can specify one or more network interfaces. In this example, we have only one interface ens3 that is configured to obtain IP addressing from a DHCP server dhcp4: yes.If there are syntax errors in the configuration, the changes will not ne applied. Once done save and close the file and apply the changes with: sudo netplan apply Verify the changes by typing: ip addr show dev ens3 3: ens3: mtu 1500 qdisc mq state UP group default qlen 1000In the Activities screen, search for “network” and click on the Network icon. This will open the GNOME Network configuration settings. Click on the cog icon. The Network interface settings dialog box will be opened: In “IPV4” Method” section, select “Manual” and enter your static IP address, Netmask and Gateway. Once done, click on the “Apply” button.Thank you for your support. Buy me a coffee Sign up to our newsletter and get our latest tutorials and news straight to your mailbox.

One is using DHCP and another is static IP assignment. DHCP or Dynamic Host Control Protocol dynamically assigns an IP address to an interface. It requires a DHCP server running in the network. In the static IP assignment, we manually assign the IP address, routing gateway, and DNS resolvers. Static IP assignment gives to more control on assigning an IP address and setting the DNS resolvers. In this tutorial, we will learn how to assign static IP address on Debian 10 “Buster” server.
