## Health v2 (maintenance only)
Score: 93/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)

## What it is
A Go-based command-line tool that tests latency and download speed across Cloudflare CDN IP ranges to find the fastest IPs (IPv4 and IPv6). It also supports speed-testing other CDNs or websites with multiple resolved IPs.

## Use cases
- find the fastest Cloudflare CDN IP for my location
- test latency and download speed of Cloudflare IP ranges
- optimize Cloudflare access from mainland China
- pick the best IP from a CDN's published IP list
- benchmark multiple resolved IPs of a website
- generate a preferred IP list for hosts file or DNS

## When to choose
- you access Cloudflare-hosted sites from a region with poor default IP assignment
- you want an automated, cross-platform CLI to rank CDN IPs by latency and speed
- you need IPv4 and IPv6 support with configurable test ranges

## When to avoid
- you need continuous network monitoring rather than one-off IP selection
- you want a GUI-based speed test
- you rely on proxying through CDN, which Cloudflare prohibits
