Cloudflare DDNS

Introduction

A Dynamic DNS application for Cloudflare that allows your zones to be constantly up-to-date with your constantly changing public IP.

Cloudflare is an excellent reverse proxy, providing powerful and complete free features like DNS resolving and CDN caching.

Description

Cloudflare DDNS is a lightweight Go application allowing your A and AAAA records to be updated with your current dynamic public IP.

It works by asking 1.1.1.1 for your public IP and then updating your configured root domain with your new public IP, if necessary. You can specify your configuration by means of a super simple yaml configuration file.
