How to configure static IP address on Ubuntu 18.04 Bionic Beaver Linux

Most likely your current Ubuntu system uses DHCP server to configure its networking settings. Hence, the configuration of your IP address is dynamic. In many scenarios, simply configuring your router or local DHCP server is a preferred way to set a static address to any host regardless of the operating system in use. Check your router manual and assign the static IP address to your host based on its MAC address using the DHCP service.
