Traceroute

Trace the network path from Network Crap's server to a public host, save runs, and compare how the path changes over time.

Traceroute is available to registered users with a verified email address. It runs real network probes from this server, so every run is tied to an account and rate-limited.

Example: trace to 8.8.8.8 DEMO

A real traceroute this server ran, shown so you can see what a finished result looks like — including the toggles below.
