IPv6 Connectivity Test

ipv6.0ms.app is a lightweight IPv6 connectivity test tool built using Caddy and Docker. It serves a simple page that:

• Detects whether your connection uses IPv4 or IPv6.
• Runs client-side checks by loading tiny images from dedicated IPv4- and IPv6-only subdomains.
• Automatically provisions HTTPS certificates via Let's Encrypt.
• (Optionally) Uses Matomo for anonymous analytics hosted at ipv60msapp.matomo.cloud.

Quick Start

1. Clone the repository:

   git clone https://github.com/bgpntx/ipv6test.git
   cd ipv6test

---

Requirements

• A server with Docker + Docker Compose installed
• Domain names with DNS records:
  • ipv6.0ms.app → A + AAAA
  • ipv4.ipv6.0ms.app → A only (no AAAA)
  • ipv6.ipv6.0ms.app → AAAA only (no A)
• Open inbound ports 80/tcp and 443/tcp to the server

---

Files

• docker-compose.yml – runs the Caddy container
• Caddyfile – defines domains and site config
• site/index.html – the test page with Spinnaker font, IPv4/IPv6 checks, and Matomo snippet
• site/ping.png – tiny 1×1 transparent PNG used for connectivity tests

Usage

1. Clone this repo (or copy the files to a directory on your server).

2. Adjust the email address in docker-compose.yml and Caddyfile for Let’s Encrypt.

3. Start the stack:

   docker compose up -d
