## What it is
A pure Bash script that updates Cloudflare DNS records with your current public IP, acting as a dynamic DNS (DDNS) updater. It is designed to run via crontab so a home network can be reached through a custom domain without a static IP.

## Use cases
- keep a custom domain pointed at my home IP without a static IP
- update Cloudflare DNS record when my ISP changes my IP
- run a dynamic DNS updater on a Raspberry Pi via cron
- access my home server remotely using a domain name
- simple bash ddns script for Cloudflare

## When to choose
- you use Cloudflare for DNS and want a dependency-free Bash solution
- you want a lightweight cron-based updater on Linux or macOS
- you prefer a simple script over running a daemon or container

## When to avoid
- your DNS provider is not Cloudflare
- you need IPv6-only handling, notifications, or multi-provider support out of the box
- you want a GUI or managed service rather than a script you configure yourself
