## What it is
A Python tool that selects high-quality Cloudflare IPs and updates DNS records via DNS provider APIs (DNSPod, Aliyun DNS, Huawei Cloud DNS) to route different lines for website acceleration. It supports IPv4/IPv6, Docker and GitHub Actions deployment, and includes protection against fake GFW wall attacks.

## Use cases
- optimize Cloudflare CDN IPs for my website
- automatically update DNS A records with best Cloudflare IPs
- speed up a site hosted behind Cloudflare in China
- set up scheduled Cloudflare IP selection with cron
- protect my site from fake wall (假墙) attacks
- run Cloudflare IP optimization via GitHub Actions or Docker

## When to choose
- you use Cloudflare as CDN with DNSPod or Aliyun DNS and want automatic line-based IP optimization
- you need scheduled updates of优选 Cloudflare IPs for IPv4 or IPv6
- you want a small self-hosted script deployable via cron, Docker, or GitHub Actions

## When to avoid
- you don't use Cloudflare or a supported DNS provider (DNSPod, Aliyun, Huawei Cloud)
- you need a fully open-source IP selection algorithm - the IP filtering itself is a closed API
- you are uncomfortable with the risk of Cloudflare account bans for IP selection usage
