A dynamic IP address is an IP address automatically allocated to a device on a network by a DHCP (Dynamic Host Configuration Protocol) server. Unlike a static IP address, which must be manually configured and remains constant, a dynamic IP address can change each time a device connects to the network or after a specified period. Dynamic IP addresses are temporary and can be reused by other devices after the device is disconnected from the network. To get a static IP address for your machine, we need to configure it. From Ubuntu 17.10 to the most recent version, Ubuntu 26.04, the network configuration utility now uses netplan. This article will show you how to install a static IP address on Ubuntu 26.04.
