## What it is
A small Alpine Linux based Docker image that uses Cloudflare's DNS API as a Dynamic DNS (DDNS) provider, keeping DNS records updated with your changing public IP. It is a multi-arch image supporting amd64, armhf, and aarch64, including Raspberry Pi.

## Use cases
- keep my home IP pointed at a cloudflare domain
- dynamic dns with cloudflare for raspberry pi
- update dns record when my public ip changes
- ddns client for ipv6 AAAA records
- run ddns in docker on arm device
- use cloudflare as dyndns provider

## When to choose
- you use Cloudflare DNS and want a lightweight, containerized DDNS updater
- you run on ARM devices like Raspberry Pi and need a multi-arch image
- you want IPv6 (AAAA) support or IP from a specific network interface like a VPN tunnel

## When to avoid
- you don't use Cloudflare as your DNS provider
- you need a DDNS client for other providers like Dyn or No-IP
- you want a non-Docker native daemon
