![]() ![]() Setting up a static IP address on Ubuntu Desktop computers requires no technical knowledge. Configuring Static IP address on Ubuntu Desktop # That’s it! You have assigned a static IP to your Ubuntu server. Verify the changes by typing: ip addr show dev ens3 2: ens3: mtu 1500 qdisc mq state UP group default qlen 1000 Once done, save the file and apply the changes by running the following command: sudo netplan apply Under nameservers, set the IP addresses of the nameservers.Under addresses: you can add one or more IPv4 or IPv6 IP addresses that will be assigned to the network interface. To assign a static IP address to ens3 interface, edit the file as follows: In this example, we have only one interface ens3 that is configured to obtain IP addressing from a DHCP server dhcp4: yes. Under the device’s type ( ethernets), you can specify one or more network interfaces. Out of the box, if you installed Ubuntu in server mode, the renderer is configured to use networkd as the back end. The configuration above also has a line that shows the renderer type. The device type can be ethernets, bonds, bridges, or vlans. The first required element is the version of the network configuration format, and the second one is the device type. Network : version : 2 renderer : networkd ethernets : ens3 : dhcp4 : yesīefore changing the configuration, let’s explain the code in a short.Įach Netplan Yaml file starts with the network key that has at least two required elements. To do so create the following file: sudo nano /etc/cloud//99-disable-network-config.cfg If your Ubuntu cloud instance is provisioned with cloud-init, you’ll need to disable it. Usually, the file is named either 01-netcfg.yaml, 50-cloud-init.yaml, or NN_interfaceName.yaml, but in your system it may be different. The name of the file may differ from setup to setup. You’ll probably find one or more YAML files in this directory. Netplan configuration files are stored in the /etc/netplan directory. In this example, the name of the interface is ens3: 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 The command prints a list of all the available network interfaces. The first step toward setting up a static IP address is identifying the name of the ethernet interface you want to configure. On Ubuntu 20.04, the system identifies network interfaces using ‘predictable network interface names’. Configuring Static IP address on Ubuntu Server # NetworkManager is mostly used on Desktop machines, while the Systemd-networkd is used on servers without a GUI. Netplan supports two renderers, NetworkManager and Systemd-networkd. To configure a network interface with Netplan, you need to create a YAMLĭescription for the interface, and Netplan will generate the required configuration files for the chosen renderer tool. Netplan configuration files are written in YAML syntax with a. The previous Ubuntu versionsĪnd its configuration file /etc/network/interfaces to configure the network. Netplan #Īs the default network management tool. Consult the vendor’s documentation for more information. The steps for configuring a DHCP reservation vary from router to router. This works by assigning a static IP to the device’s unique MAC address. 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, each time the device requests an address from the DHCP server. The easiest and recommended way to assign a static IP address to a device on your LAN is to configure a Static DHCP on your router. Configuring Static IP address using DHCP # Setting a static IP address may be required in different situations, such as configuring port forwarding or running a media server Typically, in most network configurations, the IP address is assigned dynamically by the router DHCP server. This article explains how to set up a static IP address on Ubuntu 20.04. ![]()
