## Overview

This is a small interactive Bash utility for converting an Ubuntu Server 24.04 network configuration from DHCP to a static IP. The user runs the script, reviews detected settings, supplies new values, and chooses whether to apply them; declining restores the original Netplan configuration. The README documents the workflow, but no source excerpt was available, so the relationships below reflect documented behavior only.

Main entry points: [`static-ip.sh`](https://github.com/projects-by-ac/dynamic-to-static-ip/blob/main/static-ip.sh) (Setup walkthrough)
