The Freeform Internet Exchange Project


FFIXP (the Freeform Internet Exchange) is a virtual internet exchange for connecting experimental and research networks in a reasonably safe and controlled manner. Our goal is to allow anyone access and experiment with internet backbone technologies with a low barrier to entry and extremely low cost overhead.

This project is operated, funded, and coordinated by Evan Pratten. More info and project updates may be found in his blog.

What we provide

FFIXP itself is simply an internet exchange that operates over tunnels and virtual private networks. The exchange is not geographically restricted and is not limited to a single country (although far away peers will see higher latency).

Our current infrastructure

Currently, FFIXP has backbone routers running in the following locations (more to come soon):
