Faster-than-light ping (April Fools')
A server that replies to your pings faster than ever! Now with IPv6 support. Give it a minute and the response time will go down tremendously: ping ftlping.net On Windows, add an option not to stop after 4 pings: ping -t ftlping.net Works best on MacOS and FreeBSD. Not impressive on Windows but you can see something interesting if you run a packet analyser. Report issues here: https://github.com/plingbang/ftlping/issues The code may be published when my future self passes it to me.
In plain words
Faster-than-light ping is a ping server accessible at ftlping.net that responds to network requests with decreasing response times over the course of a minute. It supports both IPv4 and IPv6 protocols and works best on macOS and FreeBSD systems. The tool is designed for developers and network administrators interested in observing interesting ping behavior, particularly when analyzed with packet analysis tools.
