Internet Measurement Networks allow anyone to participate by hosting probes that measure internet connectivity and reachability in real time. There are currently over 5,300 active probes run by over 7,000 users, providing an unprecedented view of the global internet. Participants benefit by seeing their own network from outside perspectives and tapping into thousands of vantage points. The system ensures privacy and security through authentication, restricting probes to outgoing connections only, and anonymizing personal information.
